At which temperature is the specific heat of water minimum (in $^\circ C$)?

Draw a graph of the variation of specific heat capacity of water with temperature and define calorie.

What is specific heat? Write its equation and unit,and on what does it depend?

The density of a material $A$ is $1500 \ kg/m^3$ and that of another material $B$ is $2000 \ kg/m^3$. It is found that the heat capacity of $8$ volumes of $A$ is equal to the heat capacity of $12$ volumes of $B$. The ratio of specific heats of $A$ and $B$ will be

The temperature of $5$ moles of a gas which was held at constant volume was changed from $100^{\circ}C$ to $120^{\circ}C$. The change in internal energy was found to be $80$ Joules. The total heat capacity of the gas at constant volume will be equal to ...... $J/K$.

By what property can the temperature difference be determined if the state of a substance does not change during the absorption of a given amount of heat?
