When the volume of a given mass of gas is halved and its temperature doubled, the pressure
-
A.
remains constant -
B.
increases by a factor of 4 -
C.
increases by a factor of 3 -
D.
decreases by a factor of 4
Correct Answer: Option B
Explanation
(frac{P_1V_1}{T_1}) = (frac{P_2V_2}{T_2})
V1 = 2V2 and T2 = 2T1
(frac{P_1times 2V_2}{T_1}) = (frac{P_2times V_2}{2T_1})
P2 = 4P1
