If 60 liters of hydrogen gas at 546 K is cooled to 273 K at constant pressure, what will the new volume of the gas be?

Data:-
Initial Volume=V_1=60 liter
Initial Temperature=T_1=546K
Final Temperature=T_2=273K
Final Vloume=V_2=??
Sol:-

Since the pressure is constant and the question is asking about temperature and volume, i.e,
V_1/T_1=V_2/T_2

implies V_2=(V_1*T_2)/T_1=(60*273)/546=60/2=30liter

implies V_2=30 liter

Hence the new volume of the gas is 30 liter
