366329 Which of the following is true in the case of molecules, when ice melts

366330 A solid cube of mass \({m}\) at a temperature \({\theta_{0}}\) is heated at a constant rate. It becomes liquid at temperature \({\theta_{1}}\) and vapour at temperature \({\theta_{2}}\). Let \({s_{1}}\) and \({s_{2}}\) be specific heats in its solid and liquid states respectively. If \({L_{f}}\) and \({L_{v}}\) are latent heats of fusion and vaporisation respectively, then the minimum heat energy supplied to the cube until it vaporises is

366331 \(10\;g\) of ice at \( - 20^\circ C\) is dropped into a calorimeter containing \(10\;g\) of water at \(10^\circ C\); the specific heat of water is twice that the ice. When equilibrium is reached, the calorimeter will contain

366332 A solid material is supplied with heat at constant rate and the temperature of the material changes as shown. From the graph, the false conclusion drawn is
