You use a very sensitive instrument to measure the speed of sound in your front yard in december. you repeat the test in august when the temperature is 10°c (50°f) warmer. in august, the speed of sound will be:

a: slower
b: the same
c: faster

than in december.

The speed of sound varies depending on the medium through which the sound waves travel. In addition, it varies with changes in the temperature of the medium. This is because an increase in temperature means that the frequency of interactions between the particles that transport the vibration increases, hence this increase in activity increases the speed. That is why the speed of sound in a gas is not constant, but depends on the temperature.

So, if we want the speed of sound in a gas to increase, the temperature of that gas must increase, as well.

For example, the higher the air temperature, the greater the velocity of propagation. Experiments have shown that the speed of sound in air increases for every increase in temperature.

Therefore:
