How does an air conditioner cool down a room?
In: 3
If you let a liquid evaporate, it gets cold because turning into a gas absorbs heat.
If you squish a gas until it turns liquid, it gets hot because turning back into a liquid releases all the heat it absorbed to turn into a gas.
An AC lets a liquid evaporate inside, making inside cold, and then squishes the gas back into a liquid outside, dumping the heat from inside into the outside. It’s the circle of life.
