What are the two methods for obtaining liquids from gases?
What are the two methods for obtaining liquids from gases?
Cooling the gas below its critical temperature and treating it at high pressure, or heating solids up to or beyond their melting points.
What happens to the thermal energies of molecules when a gas is cooled to form a liquid?
What happens to the thermal energies of molecules when a gas is cooled to form a liquid?
The thermal energies of molecules decrease.
How does high pressure affect the volume of a system when converting a gas to a liquid?
How does high pressure affect the volume of a system when converting a gas to a liquid?
High pressure decreases the volume of the system, allowing the molecules to come closer and increasing the forces of attraction among them.
