what is Boyle's law?

• Boyle's law relates the pressure and volume of a gas at constant temperature.
• Boyle's law relates the volume and temperature of a gas at constant pressure and amount of gas.
• Boyle's law relates the temperature and volume of a gas at constant pressure.

what is the kinetic theory?

• The kinetic theory explains the behavior of light waves.
• The kinetic theory explains the behavior of particles in matter.
• The kinetic theory explains the behavior of electrical currents.

How is a gas affected when pressure, temperature, or volume changes?

• Changes in pressure, temperature, or volume have no impact on the gas.
• The gas reacts differently depending on changes in pressure, temperature, or volume.
• The gas is affected by changes in pressure, temperature, or volume.
