Ice cubes of a total mass 80 g, and at 0 0C, are put into a chocolate drink of mass 275 g. All the icemelts as 25300 J of thermal energy transfers from the chocolate drink to the ice. The finaltemperature of the drink is 0 0C.

Ice cubes of a total mass 80 g, and at 0 0C, are put into a chocolate drink of mass 275 g. All the icemelts as 25300 J of thermal energy transfers from the chocolate drink to the ice. The finaltemperature of the drink is 0 0C.(i) Calculate the specific latent heat of fusion for ice.

The thermal energy that causes the ice to melt is transferred from the chocolate drink as itcools. The loss of this thermal energy causes the temperature of the 275 g of chocolate drinkto fall by 15 0C. Calculate the specific heat capacity of the chocolate drink.specific heat capacity=

(d) An ice cube has a temperature of −15.0 °CThe total thermal energy needed to raise the temperature of this ice cube to 0.0 °C andcompletely melt the ice cube is 5848 Jspecific heat capacity of ice = 2100 J/kg °Cspecific latent heat of fusion of ice = 334 000 J/kgCalculate the mass of the ice cube.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Mass of ice cube = _____________________________ kg(5)(Total 9 marks)Page 3 of 34
