According to the kinetic theory, what is the relationship between pressure and the number of gas molecules in a container?
  1. Pressure is independent of the number of molecules
  2. Pressure decreases with more molecules
  3. Pressure increases with more molecules
  4. Pressure is inversely proportional to the number of molecules

Questions & Step-by-Step Solutions

According to the kinetic theory, what is the relationship between pressure and the number of gas molecules in a container?
  • Step 1: Understand that gas is made up of tiny particles called molecules.
  • Step 2: Know that these molecules are constantly moving and colliding with the walls of the container.
  • Step 3: Recognize that when gas molecules collide with the walls, they exert a force on the walls.
  • Step 4: Understand that this force per unit area is what we call pressure.
  • Step 5: Realize that if you increase the number of gas molecules in the container, there will be more collisions with the walls.
  • Step 6: Conclude that more collisions mean higher pressure, assuming the temperature and volume of the container stay the same.
  • Kinetic Theory of Gases – The kinetic theory explains the behavior of gases in terms of particles in motion, relating pressure to the number of collisions between gas molecules and the walls of the container.
  • Pressure-Volume-Temperature Relationship – The relationship between pressure, volume, and temperature of a gas is described by the ideal gas law, which is foundational to understanding gas behavior.
