Give value of specific heat of gas for isothermal process.

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 heat capacity of $12$ volumes of $B$. The ratio of specific heats of $A$ and $B$ will be

If $H_C, H_K$ and $H_F$ are heat required to raise the temperature of one gram of water by one degree celcius, kelvin and fahrenheit temperature scales respectively then

Thermal capacity of a body depends on

If temperature scale is changed from $°C$ to $°F$, the numerical value of specific heat will
