Question

With the rise of temperature, the velocity of sound-
A.Decreases
B.Remains the same
C.Increases
D.Is independent of temperature

Answer 1

Hint: Temperature is a physical property of matter that quantitatively expresses hot and cold. It is the indication of thermal energy, present in all matter, which is the wellspring of the event of heat, a progression of energy, when a body is in contact with another that is colder. Temperature is estimated with a thermometer.

Complete answer:
Temperature is likewise a condition that influences the speed of sound. Heat, similar to sound, is a type of kinetic energy. Molecules at higher temperatures have more energy, in this manner they can vibrate quicker. Since the molecules vibrate quicker, sound waves can travel all the more rapidly. The speed of sound in room temperature air is 346 meters for every second. This is quicker than 331 meters for every second, which is calculated to be the speed of sound in air at frigid temperatures.
Hence, we can say from the above explanation that the speed of sound increases with increase in the temperature.

Thus, option C is the correct option.

Note:
The sound velocity is a vector whose magnitude is the sound velocity u, and whose direction is always normal outside the constant phase. The speed of sound is a property of the medium through which the sound voyages and is in this manner for the most part of more interest than the velocity itself which relies on both u and the way in which the sound is created.
