A 1.87 mol sample of Ar gas is confined in a 45.5 liter container at 23.6 °C.

If the temperature of the gas sample is raised to 46.1 °C holding the volume constant, the average kinetic energy will

a. increase
b. remain the same
c. not enough information to answer the question
d. decrease

Answer:

a. increase

Explanation:

Based on the kinetic molecular theory of gases, the average kinetic energy of the system will increase.

  • The average kinetic energy is heat
  • If temperature increases, heat of a system will also rise.
  • According the kinetic molecular theory "the temperature of the gas is a measure of the average kinetic energy of the molecules"

Therefore, due to the increase in temperature, the average kinetic energy of the system increases.
