When the absolute temperature of a gas is doubled then the correct statements are
a) The V of a gas increases by 4 times at constant P
b) The P of a gas increases by 2 times at constant V
c) The V of a gas increases by 2 times at constant P
d) The P of a gas increases by 4 times at constant V 

Options

A. b, d
B. a, c
C. b, c
D. a, d

Answer

C

Explanation

`(P_1V_1)/(T_1) = (P_2T_2)/(T_2) = (P_2V_2)/(2T_1)`.
