A new scale of temperature (which is linear) called the $W$ scale, the freezing and boiling points of water at $39º\mathrm{W}$ and $239º\mathrm{W}$ respectively. What will be the temperature on the new scale, corresponding to a temperature of $39 º\mathrm{C}$ on the Celsium scale?

If $C_{\mathrm{p}}$ and $C_{\mathrm{v}}$ denote the specific heats (per unit mass) of an ideal gas of molecular weight $M\mathit{,}$ where $R$ is gas constant, then

Liquid oxygen at 50 K is heated to 300 K at constant pressure of 1 atm. The rate of heating is constant. Which one of the following graphs represents the variation of temperature with time?

The amount of heat energy required to raise the temperature of $1 \mathrm{kg}$ of Helium at constant volume, from $T_1 \mathrm{K}$ to $T_2 \mathrm{K}$ is:-

The value of coefficient of volume expansion of glycerine is $5\times {10}^{-4} {\mathrm{K}}^{-1}$. The fractional change in the density of glycerine for a rise of $40°\mathrm{C}$ in its temperature, is:?
 

In Maxwell’s velocity distrbution cure area under the graph

A piece of ice falls from a height $h$, so that it melts completely. Only one-quarter of the heat produced is absorbed by the ice and all energy of ice gets converted into heat during its fall. The value of $h$ is :[Latent heat of ice is $3.4\times {10}^5\mathrm{J} {\mathrm{kg}}^{-1}$ and $\mathrm{g}=10 \mathrm{N} {\mathrm{kg}}^{-1}$]

Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at $100°\mathrm{C}$, while the other one is at $0°\mathrm{C}$. If the two bodies are brought into contact, then assuming no heat loss, the final common temperature is
