Water is not always liquid.
It is only liquid between 00C and 1000C. Below that it is solid, above that it is a gas.
The temperature determines how fast the atoms and molecules move about. In a solid they are too cold to move about. When they get hotter they move about relatively freely (liquid), and when they really get going, they are as free as the air!
Water vapor is different from liquid water because water vapor is a gas, and liquid water is a liquid.
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
Rain is a liquid because it is water.
Water Vapor is technically a gas and Liquid water is obviously a liquid.
