Front

Definite volume, but not definite shape

Back

Liquid: A state of matter that has a definite volume but takes the shape of its container.

Front

Liquid's resistance to flowing

Back

Viscosity: A measure of a liquid's resistance to flow; higher viscosity means a thicker liquid.

Front

When the particles in a liquid gain enough energy to form a gas

Back

Vaporization: The process by which a liquid turns into a gas when its particles gain sufficient energy.
