Charles Law Formula:

V1/T1 = V2/T2

Calculation:

V2 = V1 * T2/T1 = 1 * 546.30/273.15 = 2.000000 L

Important: Temperature must be in Kelvin for calculations. Negative Kelvin values are not physically possible.

Understanding Charles Law

Charles Law states that the volume of a gas is directly proportional to its absolute temperature when pressure is held constant. This means that as temperature increases, the volume of a gas increases proportionally. The law is named after French scientist Jacques Charles and is one of the fundamental gas laws in chemistry and physics.

Key Points

Direct Relationship

V is proportional to T (at constant P)

Absolute Temperature

Must use Kelvin scale for calculations

Constant Pressure

Pressure must remain unchanged

Ideal Gas Behavior

Assumes gas behaves ideally
