Why does a compressed air can become extremly cold when you use it?

Biology
1 answer:
BartSMP [9]3 years ago
4 0

Answer:

The reason the compressed air gets cold after being used is due to a process known as adiabatic cooling, a property of thermodynamics. A gas, initially at high pressure, cools significantly when that pressure is released. The compression needed to turn a gas to liquid allows a large amount of gas to fit in a relatively small space, and when that gas is released to a large space, it rapidly expands to fill the space.

So white blood cell’s(WBCs for short) main job is to fight infections.
They do this by swallowing the infection.


You see,WBCs do not have a permanent shape.this means that they enlarge and decrease size of parts of their body.So they grow two long arm like structures called pseudopodia which swallow the infection.(pseudopodia means false feet).
You can see the process in the photo I attached from google
