Statement 1: At constant temperature, if the pressure on a fixed mass of gas is halved, its density is doubled.
Statement 2: At constant temperature, the density of an ideal gas is directly proportional to its pressure.

Question

Statement 1: At constant temperature, if the pressure on a fixed mass of gas is halved, its density is doubled.

Statement 2: At constant temperature, the density of an ideal gas is directly proportional to its pressure.

TestHub · Accepted Answer

From d = PM/RT, at constant T, d ∝ P for a fixed gas — Statement II is correct. Halving the pressure therefore halves the density (the gas expands to twice the volume), so Statement I is incorrect. Ans: (d).
