## What is the formula for calculating speed of sound and temperature?

If the temperature is TC = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = √γRTM can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=√γRTM=√γRTM(273K273K)=√(273K)γRM√T273K≈331m/s√T273K.

## Does sound travel faster in hot or cold air?

Because sound moves faster in warm air than colder air, the wave bends away from the warm air and back toward the ground. That’s why sound is able to travel farther in chilly weather.

## At what temperature does the sound travel fastest?

At freezing (0º Celcius), sound travels through air at 331 meters per second (about 740 mph). But, at 20ºC, room temperature, sound travels at 343 meters per second (767 mph). Liquids: Sound travels faster in liquids than in gases because molecules are more tightly packed.

## What is the speed of sound in air at 45 degrees Celsius?

In a given ideal gas the speed of sound depends only on its temperature. Celsius is c = 331.3 m/s. substances.

## What is the speed of sound at 18 degrees Celsius?

The speed of sound in air is approximately 331.5 m/s at 0 °C or around 1200 km per hour. The speed of sound through air is approximately 343 m/s at normal room temperature, which is at 20 °C. The speed of sound through air is 346 m/s at 25 °C. The speed of sound in air is approximately figured out by the formula …
