D. C. Pandey Solutions for Chapter: Thermometry, Thermal Expansion and Kinetic Theory of Gases, Exercise 1: Objective Problems

Two non-reactive monoatomic ideal gases have their atomic masses in the ratio $2:3$. The ratio of their partial pressure, when enclosed in a vessel kept at a constant temperature is $4:3$. The ratio of their densities is

In a mercury thermometer, the ice point (lower fixed point) is marked as $10 °\mathrm{C}$ and the steam point (upper fixed point) is marked as $130 °\mathrm{C}$. At $40 °\mathrm{C}$ temperature, what will this thermometer read?

An aluminium sphere of $20 \mathrm{cm}$ diameter is heated from $0 °\mathrm{C}$ to $100 °\mathrm{C}$. Its volume changes by (given that coefficient of linear expansion for aluminium ${\alpha }_{{\mathrm{A}}_1}=23\times {10}^{-6} °{\mathrm{C}}^{-1}$)

A container with insulating walls is divided into two equal parts by a partition fitted with a valve. One part is filled with an ideal gas at a pressure $p$ and temperature $T$ whereas the other part is completely evacuated. If the valve is suddenly opened, then the pressure and temperature of the gas will be

Air inside a closed container is saturated with water vapour. The air pressure is $p$ and the saturated vapour pressure of water is $\overline{p}$. If the mixture is compressed to one half of its volume by maintaining temperature constant, the pressure becomes

A real gas behaves like an ideal gas, if its

The temperature of a gas contained in a closed vessel of constant volume increases by $1 °\mathrm{C}$ when the pressure of the gas is increased by $1\%.$ The initial temperature of the gas is

Kinetic energy per unit volume is $E$. The pressure exerted by the gas is given by
