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?

When all the particles are compressed, they bump into each other a whole lot. When they get sent out of the can, they can’t bump into each other as much because they have so much more space. It’s boosted by the fact that in the can, it’s a liquid, and it exits as a gas. When it transitions between the two states, it has to absorb a certain amount of energy (or release it in the case of gas to liquid).
When you compress something, it gets hot, and when you release that pressure, it gets cold. It’s the basis on which air conditioners and refrigerators work.
