Heat capacity of a substance is infinite. It means

For an ideal monatomic gas, the universal gas constant $\mathrm{R}$ is $\mathrm{n}$ times the molar heat capacity at constant pressure $C_{p} .$ Here $n$ is

When an ideal monatomic gas is heated at constant pressure, fraction of heat energy supplied which increases the internal energy of gas  is, 

Variation of molar specific heat of a metal with temperature (Temp.) is best depicted by the graph,

Two circular discs $A$ and $B$ with equal radii are blackened. These are being cooled under identical circumstances. What inference can be drawn from their cooling curves?

The graph represents
