Answer:
Sound is vibrations that travel through a medium, and which are then converted into electrical signals by our brain so that we interpret them as a noise that we hear. These vibrations consist of particles colliding with each other (this is why sound cannot travel through space; there are no particles). At warmer temperatures, the particles that make up air will move faster, so these collisions will happen more frequently. Therefore the vibrations occur more quickly, so sound travels faster and reaches our ears in a shorter amount of time.
The speed of sound can travel faster in hot air than it can in cold air. This is because the molecules of air can move even faster and the vibrations of the sound wave can transmit faster. Sound is a type of mechanical wave, meaning that it requires a medium to transmit energy. Mediums are any substance that has mass and takes up space, from the air in the room to the metal atoms in an iron fence.
