Review: Phase Changes

According to the kinetic molecular theory of matter, all matter is made of tiny

(a)   .

The particles are in constant (a)   .

(a)   energy is the energy of an object because of motion.

The measure of the speed of the moving or vibrating particles is called the (a)   .

Matter that has a definite volume and shape is called a (a)   .

If matter has a definite volume, but no definite shape it is called a (a)   .

When matter does not have a definite shape or volume it is a

(a)   .

A fourth state of matter, the (a)   state, is matter that exists at extremely high temperatures and consists of electrically charged particles.

When you add heat to matter, its thermal energy _____________________.

When you remove heat, its thermal energy __________________.
