An ice cube of mass 0.1 kg at 0°C is placed in an isolated container which is at 227°C. The specific heat s of the container varies with temperature T according to the empirical relation s = A + BT, where A = 100 cal kg–1 K–1 and B = 2 × 10–2 cal kg–1.
If the final temperature of the container is 27°C, the mass of the container is
(Latent heat of fusion of water = 8 × 104 cal kg–1, specific heat of water = 103cal kg–1 K–1)
If the final temperature of the container is 27°C, the mass of the container is
(Latent heat of fusion of water = 8 × 104 cal kg–1, specific heat of water = 103cal kg–1 K–1)
