The thermal capacity of $100 \,g$ of aluminum (specific heat $= 0.2 \,cal / g ^{\circ} C$) is ............ $cal / ^{\circ} C$.

What is specific heat? Give its unit and on which factors does specific heat depend?

Which of the following substances has the maximum specific heat capacity?

The specific heat of a substance varies with temperature as $c = 0.20 + 0.14t + 0.023t^2 \, (cal/g \cdot ^\circ C)$. The amount of heat required to raise the temperature of $2 \, g$ of the substance from $5 \, ^\circ C$ to $15 \, ^\circ C$ is: (in $, cal$)

The factor not needed to calculate heat lost or gained when there is no change of state is

If the ratio of the diameters of two spheres made of the same material is $1:2$,what is the ratio of their heat capacities?
