Questions & Step-by-Step Solutions

What is the relationship between the average kinetic energy of gas molecules and temperature?
  • Step 1: Understand what kinetic energy is. Kinetic energy is the energy that an object has because of its motion.
  • Step 2: Know that gas molecules are always moving. The faster they move, the more kinetic energy they have.
  • Step 3: Learn about temperature. Temperature is a measure of how hot or cold something is, and it relates to the energy of the molecules in a substance.
  • Step 4: Realize that when the temperature of a gas increases, the average speed of the gas molecules also increases.
  • Step 5: Understand that as the speed of the gas molecules increases, their average kinetic energy also increases.
  • Step 6: Conclude that the average kinetic energy of gas molecules is directly related to the temperature: as temperature goes up, average kinetic energy goes up.
