Options:
A) Matter cannot cease to exist
B) Ice melts and water freezes
C) Volume and pressure of a gas become zero
D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
We know that $ P=P _{0}e^{\gamma t} $ and $ V=V _{0}e^{\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 of the gas approaches zero, but the pressure does not necessarily become zero.
