What are two things that molecules can do to cause an increase pressure?

Answer 1

They can move faster, or slower.

For solids and incompressible fluids, "pressure" is the result of molecular movement, or compression by an external force.

Even apparent changes in volume, or expansion, are really the result of molecular movement, which is influenced by temperature. A rise in temperature causes a molecule's kinetic energy to increase, which is then expressed as longer or faster vibratory movements. This increased kinetic energy is what is observed as "pressure" in gas and liquid systems.

Increase in the number of molecules in the system.
Decrease in the volume of the container.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
