Which is true about gasses?

As the temperature increases, their volume increases. Molecular motion increases because temperature is the average kinetic energy of the particles.

If you decrease the pressure, the volume will also increase. The particles of the gas will see an increase in molecular motion.

As the pressure increases, so does the volume. Molecular motion increases.

As the temperature goes down the pressure increases. The particles will see a decrease in molecular motion.
