Consider the following problem about chemistry: A perfect gas at $T_1$ K and $P_1$ atm of pressure occupy $V_1$ l in volume. What volume will the same gas occupy at $T_2$ K and $P_2$ atm of pressure?

Using Ideal gas law, $\frac{P_1\cdot V_1}{T_1}=\frac{P_2\cdot V_2}{T_2}$, so the answer will be $V_2=\frac{P_1\cdot V_1\cdot T_2}{T_1\cdot P_2}$
