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=P _{0}(1+\gamma t) $ and $ V=V _{0}(1+\gamma t) $
and $ \gamma =(1/273)/{}^\circ C $ for $ t=-273{}^\circ C $ , we have $ P=0 $ and $ V=0 $
Hence, at absolute zero, the volume and pressure of the gas become zero.
