A monoatomic gas

(\gamma = 5/3)

is suddenly compressed to 1/8 of its original volume adiabatically, then the pressure of the gas, will change to

View answer and explanation

Correct option: D

32 times its initial pressure

Option D (32 times its initial pressure) is correct because the pressure changes by a factor of 32 when the volume is compressed adiabatically to 1/8 of its original volume.
