$A$ solid of $2 \,kg$ mass absorbs $50 \,kJ$ when its temperature is raised from $20^{\circ} C$ to $70^{\circ} C$. The specific heat capacity of this solid in units of $J / kg^{\circ} C$ is

What is the total energy for one mole of a solid substance?

The molar mass of a substance is $50 \, g/mol$. When $300 \, J$ of heat is supplied to a $25 \, g$ sample of this substance,its temperature increases from $30^{\circ}C$ to $50^{\circ}C$. The values of heat capacity and specific heat capacity are,respectively:

The amount of heat required to raise the temperature of a body by $1 ^\circ C$ is called its

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:

How much heat energy is supplied when $5 \,kg$ of water at $20^{\circ} C$ is brought to its boiling point? (Assume, specific heat of water $=4.2 \,J / g^{\circ} C$ )
