Which of the following is an assumption of the kinetic-molecular theory of gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

• The temperature of a gas depends on the average kinetic energy of the gas particles.

According to the kinetic molecular theory, all collisions between gas molecules are inelastic; all kinetic energy is lost.

• True

• False

Which of the following is the equation needed to calculate the kinetic energy, KE, of a moving particle?

• KE = 1/2 mv²

• KE = 2mv

• KE = mv

• KE = 1/2 m²v
