$50\,g$ of copper is heated to increase is temperature by $10\,^oC$. If the same quantity of heat is given to $10\,g$ of water, the rise in its temperature is ........ $^oC$ (Specific heat of copper $= 420\,J-kg^{-1}\,^oC^{-1}$ )

$8$

Solution

$\Delta \theta_{\mathrm{w}}=\frac{\mathrm{m}_{\mathrm{C}} \mathrm{c}_{\mathrm{C}}(\Delta \theta)_{\mathrm{C}}}{\mathrm{m}_{\mathrm{W}} \mathrm{C}_{\mathrm{W}}}$

$=\frac{50 \times 10^{-3} \times 420 \times 10}{10 \times 10^{-3} \times 4200}$

$=5^{\circ} \mathrm{C}$

If there are no heat losses, the heat released by the condensation of $x$ gm of steam at $100^o C$ into water at $100^o C$ can be used to convert $y$ gm of ice at $0^o C$ into water at $100^o C$. Then the ratio $y : x$ is nearly
