Question: What happens to the average speed of gas molecules if the temperature is increased?

Options:

  1. It decreases
  2. It remains constant
  3. It increases
  4. It becomes zero

Correct Answer: It increases

Solution:

As the temperature of a gas increases, the average speed of gas molecules also increases due to the increase in kinetic energy.

Questions & Step-by-Step Solutions

What happens to the average speed of gas molecules if the temperature is increased?
  • Step 1: Understand that gas molecules are always moving.
  • Step 2: Know that the speed of these molecules is related to their energy, called kinetic energy.
  • Step 3: Recognize that temperature is a measure of the average kinetic energy of the molecules in a gas.
  • Step 4: When the temperature increases, the energy of the gas molecules increases.
  • Step 5: As a result, the average speed of the gas molecules also increases.
  • Kinetic Molecular Theory – The theory that explains the behavior of gases in terms of particles in motion, where temperature is directly related to the average kinetic energy of the molecules.
