When we speak to each other, we force air through the small opening of our throat and shape it with our mouths. This makes the air molecules bunch together in specific patterns on their way out. Those air molecules then expand again, pushing against their neighbors, which makes them contract, and so on.
emitted by the flames strikes your skin. The energy of that radiation causes the molecules on your skin to vibrate, rotate and generally wiggle around.The more movement that a collection of particles exhibits, the higher its temperature . If the radiation from the fire transfers too much energy to your skin, the motion of your particles becomes so violent that it damages your cells, and you burn.
The same thing happens to air itself. Air and water are excellent conductors of sound, because air and water molecules are good at smoothly gliding past each other without a lot of friction, and so the sound wave just keeps repeating itself. But, occasionally the air or water molecules do crash into each other instead of maintaining the rhythm, and this adds up over time.
