Options:

A) Matter ceases to exist

B) Ice melts and water freezes

C) Volume and pressure of a gas becomes zero

D) None of these

Show Answer

Answer:

Correct Answer: C

Solution:

We know that P=P0(1+γt) and V=V0(1+γt)

and γ=(1/273)/C for t=273C , we have P=0 and V=0

Hence, at absolute zero, the volume and pressure of the gas become zero.
