Question

The density of a gas at 27'c and 1 atm is d. pressure remaining constant, at which of the following temperature will its density become 0.75 d? a) 20'c b) 30'c c) 400'c d) 300 k

Answer 1

"As per the formula where T is temperature and P is Pressure

PV = nRT

PV = m/M RT

PM = m/V RT

PM = dRT

Here,

(1) PV = d R 300

(2) PV = 0.75 d RT

From (1) and (2)

1 = 300/0.75T

T = 400 K

Hence, c is the right option for the problem.
