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.

 

Charles' Law formula

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

Where:

\(\large{ T_f }\) = 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	\(\large{ft^3}\)	\(\large{m^3}\)
