Question

How gas change back into gas when it exits the gas barrel?

Answer 1

Hello...mate...
Here is your answer......

The same way, A gas which is turned as a liquid can be again converted into gas by Increasing temperature. ... So when the compressed gas is inside thebarrel, it is in it's liquid form.But when we pass it through a pipe or something else it turns in to gasagain. Because in atmospheric pressure a gas is always a gas.
