Which of the following will increase the volume of a real gas by four times ?

A. Doubling the absolute temperature as well as pressure of the gas

B. Reducing pressure to one fourth at constant temperature

C. Reducing temperature to one fourth at constant pressure

D. Reducing the temperature to half and doubling the pressure

Answer: Option B

Solution(By Examveda Team)

According to the gas law we can write $$\frac{{{P_1}{V_1}}}{{{T_1}}} = \frac{{{P_2}{V_2}}}{{{T_2}}}$$
So by reducing the pressure to $$\frac{P}{4}$$ at constant temperature the volume increases to $$4$$ times the initial volume.
