The duster can I use always gets really cold whenever I use it for long enough. Can someone explain in the simplest way possible the reason why it gets cold?

1. There is liquid in the can.
2. This liquid evaporates creating gas in the can, which puts the contents under pressure.
3. At this certain pressure, the amount of liquid and gas remain constant.
4. When you use the duster gas, it comes out of the can reducing the pressure.
5. To keep the pressure in constant, the liquid evaporates into a gas.
6. Energy is needed for a liquid to turn into a gas so the can goes cold.
