Physical science final

The kinetic theory of matter states that atoms and molecules are

• Particles of all matter

• Always in random motion

• What compose solids, liquids, and gases

• Always emitting energy of some form

The warmer an object is, the greater is its

• Thermal energy

• Conductivity

• Radiation potential

• Potential energy

• Rotational motions

• Vibratory motions

• All of the above
