Q. Absolute zero $(0\ K)$ is that temperature at which
A) Matter ceases to exist
B) Ice melts and water freezes
C) Volume and pressure of a gas becomes zero
D) None of these
Explanation
(c) We know that $P = P_{0}(1 + \gamma t)$ and $V = V_{0}(1 + \gamma t)$
And $\gamma = (1/273)/℃$ for $t = - 273℃,$ we have $P = 0$ and $V = 0$
Hence, at absolute zero, the volume and pressure of the gas become zero
