Front

What is the definition of pressure in the context of gases?

Back

Pressure is the force exerted by gas molecules colliding with the walls of their container.

Front

What is the relationship between temperature and gas volume at constant pressure?

Back

As temperature increases, the volume of a gas increases (Charles's Law).

Front

What is the relationship between pressure and volume at constant temperature?

Back

As volume decreases, the pressure of a gas increases (Boyle's Law).

Front

What happens to gas molecules when they are heated?

Back

They gain energy and move faster, causing the gas to expand.
