heater is switched on. mixture, time t elapsed in the process of melting of ice and time t2 at a constant rate by a heater to the mixture. The graph shows temperature of the mixture for a portion of a time interval after the Assuming heat loss to the surroundings and heat capacity of the heat of water is sw = 4.2 kJ/(kg-°C), specific latent heat of fusion of ice is L=0.33 MJ/kg and melting point of ice is = 0°C. Now heat is supplied water at temperature & = -21.0 °C is kept in a calorimeter. Total mass Under certain conditions, a mixture of crushed ice and super cooled Unde at temperature & =-21.0 °C is kept in a calorimeter. Total mass wane mixture is m = 0.60 kg. Heat capacities of water and ice in the 01rimeter are equal. Specific heat of ice is s; = 2.1 kJ/(kg°C), specific %3D pe 33 MJ/kg and melting point of ice is 6 =0°C.
