Ideal Gas Law Workspace

What PV = nRT is actually saying

Pressure, volume, and temperature of a gas are linked. Change one while holding the others constant, and the ideal gas law tells you exactly how the rest respond, assuming the gas behaves "ideally" — particles with negligible volume and no intermolecular forces.

When the "ideal" assumption breaks down

Real gases deviate from this law at very high pressure or very low temperature, where molecules are packed close enough that their size and mutual attraction actually matter. For everyday, classroom-level problems, the ideal approximation holds up well.
