What is the relationship between the pressure and volume of a gas at constant temperature according to the kinetic theory?
  1. Pressure is directly proportional to volume.
  2. Pressure is inversely proportional to volume.
  3. Pressure is independent of volume.
  4. Pressure is proportional to the square of the volume.

Questions & Step-by-Step Solutions

What is the relationship between the pressure and volume of a gas at constant temperature according to the kinetic theory?
  • Step 1: Understand that gases are made of tiny particles that are always moving.
  • Step 2: Know that temperature is a measure of how fast these particles are moving.
  • Step 3: Recognize that when the temperature is constant, the speed of the gas particles does not change.
  • Step 4: Learn that pressure is the force that gas particles exert when they hit the walls of their container.
  • Step 5: Realize that if you decrease the volume of the container, the gas particles have less space to move.
  • Step 6: Understand that with less space, the gas particles hit the walls more often, which increases the pressure.
  • Step 7: Conclude that if you increase the volume, the gas particles have more space, hit the walls less often, and the pressure decreases.
  • Step 8: Therefore, pressure and volume are inversely related: as one goes up, the other goes down, at constant temperature.
