What happens when a gas is changed to a liquid?
The explanation is given below.
The molecules in a gas are far apart and free to move from each other,
while in a liquid, they are bound to be closer with each other.
The temperature regime which is responsible depends on the pressure also.
The vapour pressure makes any element to be in the state of liquid, solid or gas.
temperature and vapour pressure are the two critical parameters to decide the state of an element
