Question

Densities of two gases are in the ratio of 1 : 2 and their temperature are in the ratio of 2 : 1, then the ratio of their pressure is

• A. 1:01
• B. 1:02
• C. 2:01
• D. 4:01

Answer 1

Answer: (A)

1:01

Answer 2

P $\propto$ d and T $\therefore \, \frac{P_1}{P_2} = \frac{d_1T_1}{d_2T_2} = \frac{1}{2} \times \frac{2}{1}$ $\therefore$ $P_1 : P_2 = 1 : 1$
