What is the ideal gas law equation?

Back

PV = nRT

Front

Define pressure in the context of gases.

Back

Pressure is the force exerted by gas particles colliding with the walls of a container.

Front

What is the standard temperature and pressure (STP) for gases?

Back

0°C (273.15 K) and 1 atm.

Front

What happens to the volume of a gas when the temperature increases at constant pressure?

Back

The volume increases (Charles's Law).

Front

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

Back

As pressure increases, volume decreases (Boyle's Law).
