Waves are made by the oscillation (up, down and sideways movement) of partials. When partials oscillate, they transfer energy by bumping into each other.
<em>Sound wave are waves that are created by the </em><em>oscillation of air particles </em><em>and carry </em><em>sound energy</em><em> from point A to point B. </em>
<em />
In a warm room, the air particles have <em>higher energy</em> compared to a cold room. Hence, they bump into each other <em>more frequently. </em>
This allow them to transfer the sound energy <em>quickly and easily </em>from one partial to another.
Hence, sound travels faster in warm room then in cold room.
Sound travels outwards from the source in all directions. So there you have it sound does travel faster in warm air BUT it may appear to travel farther in cold air. This is how that works……if the air close to the ground is colder than the air above it then sound waves travelling upwards will be bent downwards.
