MCQ
Absolute zero $(0\, K)$ is that temperature at which
  • A
    Matter ceases to exist
  • B
    Ice melts and water freezes
  • Volume and pressure of a gas becomes zero
  • D
    None of these

Answer

Correct option: C.
Volume and pressure of a gas becomes zero
c
(c) 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.
