Why does sound travel slower in cold air than in warm 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.
Is sound louder in hot or cold air?
In terms of temperature, sound waves move faster in warm air and slower in cold air. This means the sound would be louder and you could hear the traffic noise from farther away. During the daytime it’s very hot at the surface, and sounds refracts the other way, up into the atmosphere, and away from our ears.
Why does sound travel faster at night?
At night , the air is denser due to humidity (obviously nights are cooler). sound requires medium to travel and so DENSER the medium,FASTER the sound travels. Humid air is denser than warmer air as in day. When something is dense, the light moves slower but sound moves faster.
Why does sound travel faster in moist air?
As moist will decrease the density of air particles(water vapor is lighter than diatomic Oxygen (32 units) and diatomic Nitrogen (28 units) at constant temperature and pressure. so the speed of sound will increase. Hence the sound will travel faster in moist air than the dry air.
