The velocity of sound in air
The velocity of sound in air increases with increasing temperature. This is because warmer air has more energy, causing air molecules to move faster and transmit sound waves more quickly.

The velocity of sound in air increases with increasing temperature. This is because warmer air has more energy, causing air molecules to move faster and transmit sound waves more quickly.
The velocity of sound in air is significantly influenced by temperature. As the temperature increases, the speed of sound in air also increases. This happens because warmer air causes air molecules to gain more kinetic energy, which makes them vibrate and collide more quickly, facilitating faster transmission of sound waves. Conversely, as the temperature decreases, the speed of sound decreases because the air molecules have less kinetic energy, resulting in slower vibrations and collisions. The relationship between temperature and the speed of sound can be quantified using the formula:
v = 331.3 + 0.6 x T
where 𝑣 is the speed of sound in meters per second and 𝑇 is the temperature in degrees Celsius. Hence, colder temperatures lead to a slower speed of sound. Therefore, the correct answer is; option [D] decreases with decreasing temperature.
