Specific Heat Capacity

At a given temperature, the specific heat of a gas at constant pressure is always greater than its specific heat at constant volume.

A source of heat supplies heat at a constant rate to a solid cube. The slope of portion $\mathrm{CD}$ of the graphs gives :-

Calorie is defined as the amount of heat required to raise temperature of $1 \mathrm{g}$ of water by $1°\mathrm{C}$ and it is defined under which of the following conditions :-

The quantities of heat required to raise the temperatures of two copper spheres of radii $r_1 \mathrm{a}\mathrm{n}\mathrm{d} r_2 (r_1=1.5r_2)$ through 1 K are in the ratio of

At a given temperature, the specific heat of a gas at constant pressure is always greater than its specific heat at constant volume.

For three gases (assume ideal); oxygen, nitrogen and carbon dioxide, (C_p - C_v) will be

One mole of an ideal monoatomic gas at temperature T₀ expands slowly according to the law $\frac{P}{V}=\text{constant.}$ If the final temperature is 2T₀, heat supplied to the gas is

A copper block of mass $2.5 \mathrm{kg}$ is heated in furnace to a temperature of $500° \mathrm{C}$ and then placed on a large ice block. What is the maximum amount of ice that can melt ? (Specific heat of copper is $0.30 \mathrm{J} {(\mathrm{g}-\mathrm{K})}^{-1}$; heat of fusion of water is $335 \mathrm{J} {\mathrm{g}}^{-1}$)

If one mole of a monoatomic gas $\left(\gamma =5/3\right)$ is mixed with one mole of a diatomic gas $\left(\gamma =7/5\right)$ , the value of γ for the mixture is

$70 \mathrm{cal}$ of heat is required to raise the temperature of  $2 \mathrm{moles}$ of an ideal diatomic gas at constant pressure from $30°\mathrm{C}$ to $35°\mathrm{C}$. The amount of heat required (in calorie) to raise the temperature of the same gas through the same range $(30°\mathrm{C} \mathrm{to} 35°\mathrm{C})$ at constant volume is
