Questions & Step-by-Step Solutions

What is the effect of increasing the number of gas molecules in a container at constant temperature and volume?
  • Step 1: Understand that gas molecules are tiny particles that move around in a container.
  • Step 2: Recognize that temperature is a measure of how fast these molecules are moving.
  • Step 3: Know that volume is the amount of space inside the container where the gas is held.
  • Step 4: When you increase the number of gas molecules in the container, you are adding more particles.
  • Step 5: More gas molecules mean more particles are moving around and hitting the walls of the container.
  • Step 6: Each time a gas molecule hits the wall, it exerts a force on the wall.
  • Step 7: With more molecules hitting the walls, the total force on the walls increases.
  • Step 8: Pressure is defined as the force exerted on a certain area, so if the force increases, the pressure also increases.
  • Step 9: Therefore, increasing the number of gas molecules at constant temperature and volume results in increased pressure.
