Vedclass · Answer

(D) According to Charles's Law,for a fixed mass of gas at constant pressure,the volume is directly proportional to its absolute temperature $(V \propto T)$.Initial temperature $T_1 = 20 + 273.15 = 293.15 \, K$.Final temperature $T_2 = 40 + 273.15 = 313.15 \, K$.Since $T_2 > T_1$,the volume $V$ must increase as $V_2 = V_1 	imes (T_2 / T_1)$.Therefore,the volume increases.

When a gas is heated at constant pressure from $20\,^oC$ to $40\,^oC$,its volume:
