Charles' Law

Written by Jerry Ratzlaff on . Posted in Thermodynamics

charles law 1Charles' 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  \(\large{ V_i \; T_f = V_f  \; T_i   }\) 
Symbol English Metric
\(\large{ T_f }\) = 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 \(\large{ft^3}\) \(\large{m^3}\)
