Question: What happens to the average kinetic energy 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: 

The average kinetic energy of gas molecules is directly proportional to the absolute temperature. Therefore, increasing the temperature increases the average kinetic energy.

Questions & Step-by-Step Solutions

What happens to the average kinetic energy of gas molecules if the temperature is increased?
  • Step 1: Understand that gas molecules are always moving. This movement is called kinetic energy.
  • Step 2: Know that temperature is a measure of how hot or cold something is, and it relates to the energy of the molecules.
  • Step 3: Learn that there is a special scale called absolute temperature (measured in Kelvin) that scientists use to measure temperature in relation to energy.
  • Step 4: Remember that the average kinetic energy of gas molecules increases when the temperature increases.
  • Step 5: Conclude that if you raise the temperature of a gas, the average kinetic energy of its molecules will also increase.
  • Kinetic Energy and Temperature Relationship – The average kinetic energy of gas molecules is directly proportional to the absolute temperature, meaning that as temperature increases, so does the average kinetic energy.
