Study Notes

The Liquid State

Liquids possess higher density compared to gases, occupying a specific volume and density due to van der Waals forces.
Liquids are relatively incompressible, meaning their volume does not change significantly under pressure.
As fluids, liquids do not have a definite shape, adapting to the shape of their container similar to gases.
Transitions between gas and liquid states, as well as from liquid to solid, are influenced by temperature and pressure conditions.
Cooling a gas decreases its kinetic energy, which results in a reduction in the velocity of the gas molecules.
When pressure is increased on a gas, molecules come closer, allowing van der Waals forces to induce a phase change to the liquid state.
