States of Matter Ch 12 H

The kinetic molecular theory describes the behavior of matter in terms of particles in motion.

• True

• False

An elastic collision is one where two colliding particles both lose some of their kinetic energy.

• True

• False

Temperature is defined as the average kinetic energy of the particles in a sample of matter.

• True

• False

Forces that act between two molecules are referred to as intermolecular forces.

• True

• False

Both gases and liquids can be classified as fluids because of their ability to flow.

• True

• False

A substance does not change in temperature while it is undergoing a change in state.

• True

• False

Boiling occurs when the vapor pressure from a liquid is equal to the atmospheric pressure.

• True

• False

The kinetic-molecular theory assumes that the distance between the particles of a gas is so large that there are no significant attractive or repulsive forces.

• True

• False

The surface tension of water decreases when a detergent is added to it.

• True

• False
