## User Guide

This tool will calculate any parameter from the equation defined by Charles’ law V₁/T₁ = V₂/T₂, which includes the V_{1} gas volume, T_{1} gas temperature, V_{2} gas volume and T_{2} gas temperature.

Charles’ law explains that for an ideal gas, the volume of the gas is directly proportional to the temperature of the gas, as long as the pressure and quantity of gas is unchanged.

### Formulas

Charles’ Law is explained with math in the following ways.

The volume of an ideal gas is proportional to its temperature:

V ∝ T

The Volume divided by the temperature of the gas in a given state, equals a constant value:

V / T = Constant

The division of volume by temperature for an ideal gas in one state, equals the division of volume by temperature for an ideal gas in another state, as long as the pressure and quantity of gas does not change between the two states.

V_{1} / T_{1} = V_{2} / T_{2}

The formulas used by this Charles’ law calculator to determine each individual parameter are:

V_{1} = V_{2} · T_{1} / T_{2}

T_{1} = T_{2} · V_{1} / V_{2}

V_{2} = V_{1} · T_{2} / T_{1}

T_{2} = T_{1} · V_{2} / V_{1}

#### Symbols

- V
_{1}= Volume of the first gas state - T
_{1}= Temperature of the first gas state - V
_{2}= Volume of the second gas state - T
_{2}= Temperature of the second gas state

### V_{1}

This is the total volume occupied by the first gas state.

### T_{1}

This is the temperature of the first gas state.

### V_{2}

This is the total volume occupied by the second gas state.

### T_{2}

This is the temperature of the second gas state.
