100 gm of copper is heated to increase its temperature by $21^\circ C$. If the same amount of heat is given to 50 gm of water, then the rise in its temperature is (Specific heat of Cu = $400~J~kg^{-1}K^{-1}$, Water = $4200~J~kg^{-1}K^{-1}$):

A metal block of mass \(3.3\,\text{kg}\) is heated to a temperature of \(400^\circ\text{C}\) and then block is placed on a large ice block. The specific heat of the metal is \(0.4\,\text{J g}^{-1}\text{K}^{-1}\) and heat of fusion of water is \(330\,\text{J g}^{-1}\). The maximum amount of ice that can melt is

The amount of heat needed to heat \(200\,\text{g}\) of ice at \(-10^\circ\text{C}\) to convert it into water at \(30^\circ\text{C}\) is:
\[ \text{Specific heat capacity of ice}=2100\,\text{J kg}^{-1}\text{K}^{-1} \] \[ \text{Specific heat capacity of water}=4186\,\text{J kg}^{-1}\text{K}^{-1} \] \[ \text{Latent heat of fusion of ice}=3.35\times10^5\,\text{J kg}^{-1} \]

5 g of ice at \(-30^\circ C\) and 20 g of water at \(35^\circ C\) are mixed together in a calorimeter. The final temperature of the mixture is

A steel rod of length 5 m and radius 2 cm is kept at room temperature and heated to 10°C above room temperature. The change in the cross-sectional area of the rod is (coefficient of linear expansion = \(10 \times 10^{-6} \, ^\circ\text{C}^{-1}\)).

A small electric heater is used to heat \(200\,\text{g}\) of water. The time required to bring all this water from \(40^\circ\text{C}\) to \(100^\circ\text{C}\) is \(200\,\text{s}\). If specific heat of the water is \(4200\,\text{J kg}^{-1}\text{K}^{-1}\), then the power supplied by the heater is
