Question

A flask is filled with 13 g of an ideal gas at 27 ° C and its temperature is raised to 52 ° C . The mass of the gas that has to be released to maintain the temperature of the gas in the flask at 52 ° C , the pressure remaining the same is, 2 . 5 g, 2 . 0 g, 1 . 5 g, 1 . 0 g

PV ∝ Mass of gas × Temperature In this problem pressure and volume remain constant, so M 1 T 1 = M 2 T 2 = constant ∴ M 2 M 1 = T 1 T 2 = 2 7 + 2 7 3 5 2 + 2 7 3 = 3 0 0 3 2 5 = 1 2 1 3 ⇒ M 2 = M 1 × 1 2 1 3 = 1 3 × 1 2 1 3 g = 1 2 g i.e., the mass of gas released from the flask = 13 g - 12 g = 1 g .
