Question

The density of neon will be minimum at ?

• A. $STP$
• B. $0^{\circ }C$, $2$ atm
• C. ${273}^{\circ }C$,$1$ atm
• D. ${273}^{\circ }C$, $2$ atm

Answer 1

Answer: (C)

${273}^{\circ }C$,$1$ atm

Density of neon,

$d=\frac{P}{RT}$. . . . . . . .(1)

From equation (1),

$d\propto \frac{P}{T}$

The density of neon will be minimum when Pressure $P$ is minimum and temperature $T$ is maximum.

Thus, (C) is the correct choice for the answer.
