For a given quantity of gas, $\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}$ $(P_1V_1)/T_1 = (P_2V_2)/T_2$

Explanation:

Of course, when $P_{1} = P_{2}$ $P_1 =P_2$ , we get Charles' Law, $\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$ $V_1/T_1 = V_2/T_2$ . And when $T_{1} = T_{2}$ $T_1=T_2$ , we get Boyle's law, $P_{1} V_{1} = P_{2} V_{2}$ $P_1V_1 = P_2V_2$ . Combining the two laws, we get $P V$ $PV$ $=$ $=$ $k$ $k$ . Once we introduce $n$ $n$ , the molar quantity of gas, and a suitable constant, we get the Ideal Gas Law.
