Another way to explain this is having a heavy metal band play at a bar. With all those bodies just waiting for the band to play they are not too active. The air in within the enviroment is moderately cool.
Once the band begins to play, the bodies begin to get excited and then start headbanging and attempt to form mosh pits. The air in the enviroment begins to get warmer, cause the movement of bodies produce heat.
When you start headbanging and joining in mosh pits, you need some type of space, dont you?
the band = the variable that excites the water molecules
the bar = the contained enviroment
the bodies = water molecules
It's how I explained it to my son. He is into science and hard rock.
