# What happens to the speed of sound when the temperature decreases

The speed of sound in air (m/s) depends on temperature according to the approximate expression v=331.5+0.607Tc Where, Tc is the celsius temperature. In dry air, the temperature decreases about 1 degree C for every 150m rise in altitude. (a)Assume this change is constant up to an altitude of 9,000m.

Sound travels about 1500 meters per second in seawater. Sound travels much more slowly in air, at about 340 meters per second. The speed of sound in seawater is not a constant value. It varies by a small amount (a few percent) from place to place, season to season, morning to evening, and with water depth. Answer: C. Because when the temperature is minus 25, the speed of sound would be about 1,137 kilometres per hour, or about 10 per cent slower. The speed of sound changes by about . 6 metres per second for every degree. The speed of sound in air (m/s) depends on temperature according to aprox expression of v= 331.5 + 0.607 Tc Tc= temp in celcius In dry air, temperature decreases about 1deg celcius for every 150m rise in altitude. A) assume the change is constant up to . Math. The air temperature decreases by about 1 degree Fahrenheit for each 300 feet of altitude. The speed of sound in air (in m/s) depends on temperature according to the approximate expression v = 331.5 + 0.607TC where TC is the Celsius temperature. In dry air the temperature decreases about 1 C for every 150 m rise in altitude. At 40,000 feet, where the temperature is –55 C, the speed of sound decreases to 574 knots. In high-speed flight and/or high-altitude flight, the measurement of speed is expressed in terms of a “Mach number”—the ratio of the true airspeed of the aircraft to the speed of sound …

For example, sound is a mechanical wave that travels through a fluid or a solid. The speed of sound in air with an atmospheric pressure of 1.013 x 10 5 Pa and a temperature of 20 C is v s ≈ 343.00 m/s. Because the density depends on temperature, the speed of sound in air depends on the temperature of the air. This will be discussed in detail

Answer: 1. The speed of sound will also change. 2. The sound travle faster when temperature decreases and vice versa. The speed of sound in air in fact depends on the temperature of the air. At 0 o C, the speed of sound in air is 331.5 m/s. For every Celsius degree above 0 o C, the speed increases by 0.6 m/s. For every Celsius degree below 0 o C, the speed decreases by 0.6 m/s. PLEASE, SHOW ME HOW TO DO IT. As the temperature of the medium increases, so does the speed of sound. As the temperature decreases the speed of sound decreases (this is true for air, at least). To calculate speed of sound in... Temperature affects the speed of sound because temperature can affect the “elastic” qualities of different mediums. At the very basics lower temperatures will decrease the speed of sound while higher temperatures will increase the speed of sound, all other factors being equal. The speed of sound in air (in meters per second) depends on temperature according to the approximate expression v 5 331.5 1 0.607TC where TC is the Celsius temperature. In dry air, the temperature decreases about 18C for every 150-m rise in altitude. (a) Assume this change is … Since the temperature is now constant, the pressure of the water has the largest effect on sound speed. Because pressure increases with depth, sound speed increases with depth. Salinity has a much smaller effect on sound speed than temperature or pressure at most locations in the ocean.

What happens the temperature as one move from the equator to the poles?... Thus, as the temperature of the medium decrease, the speed of sound decreases. So in the summer.

Why does the speed of a sound wave increase as it moves into deep water? A. Because sound waves travel faster as water temperature decreases, and water temperature decreases with depth. B. Because sound waves travel faster in denser media, and water density increases with depth. C. The speed of sound has much to do with the temperature. At 20 C the speed of sound is 343 m/s. If the temperature decreases also the speed of sound decreases. Raquel Janes Ms. Satinof 10/23/16 What do you think happens to the speed of sound based on the temperature, salinity, and pressure profiles depicted above? Sound decreases as depth increases but increases as temperature increases. The speed of a note created by a flute will increase as the speed of sound increases. When a marching band goes outside on a cold day, pose a hypothesis as to what would happen to the note played on a flute. A) It would decrease because the speed of sound and temperature are proportional. The speed of light in water is 3⁄4 of the speed in light of air. This has what affect on ocean water?... Density increases and temperature decreases... Most efficiently in the ocean? Blue. What visible spectrum of light is transmitted least efficiently in the ocean? Red. What happens to the speed of sound in the ocean? Increases as What happens to the speed of sound as the temperature increases? A. Constant B. Decreases C. Increases D. Cannot be determined Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature.

This is significantly faster than the speed of sound in air—approximately 343 m/s (but this value changes a little bit depending on the air temperature). Overall, it's a great view of the

The speed of a note created by a flute will increase as the speed of sound increases. When a marching band goes outside on a cold day, pose a hypothesis as to what would happen to the note played on a flute. A) It would decrease because the speed of sound and temperature are proportional. So, it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. While not negligible, this is not a strong dependence. At 0 C it is 343 m/s, less than a 4% increase. Figure 3 shows a use of the speed of sound by a bat to sense distances. For each degree increase in air temperature above 0 degrees Celsius, the speed of sound in air increases about ____ m/s. .60 The speed of sound at normal room temperature is about ___. Sound - Sound - Refraction: Diffraction involves the bending or spreading out of a sound wave in a single medium, in which the speed of sound is constant. Another important case in which sound waves bend or spread out is called refraction. This phenomenon involves the bending of a sound wave owing to changes in the wave’s speed. Refraction is the reason why ocean waves approach a shore Answer: C. The speed decreases - Speed of sound is directly affected by the temperature of the medium. The hotter the medium the faster the sound travels. The colder the medium the slower the sound travel. #CarryOnLearning

Temperature usually decreases with depth and normally exerts a greater influence on sound speed than does the salinity in the surface layer of the open oceans. In the case of surface dilution, salinity and temperature effects on the speed of sound oppose each other, while in the case of evaporation they reinforce each other, causing the speed 1. The speed of sound decreases when the temperature decreases. 2. Sound travels faster when temperature increases, since the molecules vibrate faster.

Two things: The speed of sound in air is approximately proportional to the square root of the absolute temperature (over a fairly wide range of temperatures). The reason is that it is inversely proportional to the square root of the mass density o... The temperature decreases more slowly, density is still increasing of course, and sound speed starts to increase, from about 1000m down: In most of the ocean except for the polar regions where salinity varies more than temperature, temperature controls the sound speed. Pressure is important in the deeper ocean where temperature is more uniform.

Because the speed of sound increases with air temperature, and air temperature generally decreases with altitude, the true airspeed for a given Mach number generally decreases with altitude.  As an airplane moves through the air faster, the airflow over parts of … Which factors affect the speed of sound? Type and volume of medium temperature and type of medium volume and temperature of medium... As elevation increases, temperature decreases. At which elevation will sound travel fastest? 500 meters 1,000 meters 1,500 meters 2,000 meters. The reducing density means you need to speed up to fly at the same dynamic pressure, and; the atmospheric lapse rate decreases the speed of sound in air. Both effects conspire to reduce the stall angle of attack at 30.000 ft to a value quite a bit below that at sea level. Details depend on the airfoil and specifically on its nose radius and The speed of sound in air (in m/s) depends on temperature according to the approximate expression v = 331.5 + 0.607TC where TC is the Celsius temperature. In dry air the temperature decreases about 1 C for every 150 m rise in altitude. A) The speed of sound should increase as it solidifies. B) The speed of sound should decrease as it solidifies. C) The speed of sound does not change because the chemical is still H2O. D) The speed of sound only changes with temperature. Ice freezes at a constant temperature. The rate of speed at which sound travels increases with temperature, higher water salinity and higher levels of water density. 10. Sound speed is affected by the oceanographic variables of temperature, salinity, and pressure. We can look at the effect of each of these variables on the sound speed by focusing on one spot
