# Charles' Law

Charles' law, one of the gas laws, states that at a constant pressure the volume of a given mass of gas is directly porportional, increases or decreases, to the absolute temperature.

\(\large{ \frac{V_i}{T_i} = \frac{V_f}{T_f} }\) or \(\large{ \frac{V_f}{V_i} = \frac{T_f}{T_i} }\) or \(\large{ V_i \; T_f = V_f \; T_i }\) | ||

\(\large{ T_f }\) = final temperature | \(\large{F}\) | \(\large{C}\) |

\(\large{ T_i }\) = initial temperature | \(\large{F}\) | \(\large{C}\) |

\(\large{ V_f }\) = final volume | \(\large{ft^3}\) | \(\large{m^3}\) |

\(\large{ V_i }\) = initial volume | \(\large{ft^3}\) | \(\large{m^3}\) |
