The Nature of Gases

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

• True

• False

A device that is used to measure atmospheric pressure.

• Barometer

• Thermometer

• Manometer

• Odometer

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

• The pascal (Pa)

• The millimeters of mercury (mm Hg).

• The milliliter (mL)

• The atmosphere (atm)

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

• True

• False

The kelvin temperature of a substance is inversely proportional to the average kinetic energy of the particles of the substance.

• True

• False

Absolute zero the temperature at which the motion of particles theoretically ceases.

• True

• False
