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

The specific heat capacity of a copper block of mass $M$ is $s$. If the mass of the copper block is doubled,the specific heat capacity will be

The quantities of heat required to raise the temperature of two solid copper spheres of radii $r_{1}$ and $r_{2}$ $(r_{1} = 1.5 r_{2})$ through $1 \ K$ are in the ratio:

If the specific heat of a substance is infinite,it means

Is the molar specific heat of a solid a constant value? Explain.

Two substances $A$ and $B$ of the same mass are heated at a constant rate. The variation of temperature $\theta$ of the substances with time $t$ is shown in the figure. Choose the correct statement.
