What two factors principally affect the sped of sound in a gas?

1) temperature

2) the relative humidity of the air

Explanation:

1) Temperature of the gas primarily affects the speed of sound in a gas.

2) Air is a mixture of gases and water vapor, the humidity of the air will have an effect on the speed of sound.

Answer: temperature and

Explanation: temperature and

and humidity the most essential factor affecting the speed of sound in gas ... in gas, sound speed changes with change in temperature. For stable temperature, the speed of sound is independent of pressure. For every increase in temperature, there is a corresponding increase in thermal energy as molecules do resonate faster. Humidity has little effect on the speed of sound. The speed of sound also depends on d relationship between molecules in gas
