The kinetic theory of matter states _________________. All particles of matter are moving
_______ means “having no form.amorphous
_______ have vibrating particles that don’t have enough energy to move out of position.solids
_______ solids have particles arranged in repeating geometric patterns. crystalline
_______ have enough energy to move over each other, but not enough energy to separate from each other. liquid
_______ have particles with enough energy to separate from each other and move about freely. gas
_______ is a gas-like mixture of positively and negatively charged particles. plasma
_______ _______ explains why matter expands when heated and contracts when cooled. Thermal expansion
Why is it easier to remove a tight jar lid by running hot water over it than by prying it off with a knife? The hot jar lid has caused the metal to expand so it is not as tight on the glass jar
