Question

Which of the following methods will enable the volume of an ideal gas to be made four times

• A. Double the absolute temperature and pressure
• B. Halve the absolute temperture and double the pressure
• C. Quadraple the absolute temperature at constant pressure
• D. Quarter the absolute temperature at costant pressure

Answer 1

Answer: (C)

Quadraple the absolute temperature at constant pressure

PV = nRT {$\therefore Fromidealgasequation$}
Now this gives $V=\frac{nRT}{P}$
if pressure is maintained constant and temperature is made 4 times (quadrupled), then volume also becomes 4 times
So, C is the correct answer.
