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?

Imagine the duster can as a magic spray bottle. When you press the button, the magic inside the can starts to come out. But this magic isn’t like the usual water or juice you might spray from a bottle.
Inside the can, there is a special kind of gas that is squeezed really tightly. When you press the button, the gas gets released and starts to expand, just like a balloon being blown up. But when the gas expands, it needs more space, so it takes the space around it.
But here’s the interesting part: When the gas takes up more space, it actually needs to use some energy to do that. It’s like doing a little bit of exercise for the gas. And when it uses energy, it starts to feel colder.
So, when you use the duster can for a while, the gas inside keeps expanding and using energy, which makes it get colder and colder. That’s why you feel it getting chilly when you hold the can for too long.
But remember, even though it gets cold, the duster can isn’t meant to be used for cooling things. It’s designed to blow away dust and dirt, so be careful and use it only for its intended purpose
