Kinetic Theory and Thermal Energy

Front

What is thermal energy?

Back

The sum of the kinetic and potential energy of all the particles of an object.

Front

What type of kinetic energy do solids have?

Back

Low kinetic energy.

Front

What is the volume and shape of liquids?

Back

Liquids have a definite volume but not a definite shape.

Front

What effect does heating have on the thermal energy of an object?

Back

Heating increases the thermal energy of an object.

Front

What is the shape and volume of solids?

Back

Solids have a definite volume and definite shape.

Front

What is kinetic theory?

Back

A theory that explains the behavior of matter in terms of particles in motion.

Front

How does temperature relate to thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What happens to the kinetic energy of particles in a substance as it is heated?

Back

The kinetic energy of the particles increases.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What state of matter has particles that are closely packed together and vibrate in place?

Back

Solids.
