According kinetic theory, all matter consists of tiny particles that aren't in constant motion.

• True

• False

The particles in a ................... are considered to be small, hard spheres with an insignificant volume

• solid

• liquid

• gas

• True

• False

All collisions between particles in a gas are perfectly elastic.

• True

• False

During an elastic collision, kinetic energy is transferred without loss from one particle to another, and the total kinetic energy doesn't remain constant.

• True

• False

A device that is used to measure atmospheric pressure.

• Barometer

• Thermometer

• Manometer

All these units are units of pressure except..........

• The pascal (Pa)

• The millimeters of mercury (mm Hg).

• Liter (L)

Potential energy speed up the particles

• True

• False

An increase in the average kinetic energy of the particles causes the temperature of a substance to rise.

• True

• False
