Answer:
Explanation:
from ideal gas equation, PV = nRT
So, this gives V=
P
nRT
so, V is proportional to absolute temperature and inversely proportional to the pressure of the gas
Now temperature is made half and pressure is made 2 times
So, clearly the volume becomes one-fourth of it's original value.
So, B is the correct answer.
