Energy is transferred to 15.5kg of ice at 0 ∘ C until it is all melted, but without any temperature change. If the latent heat of fusion of water is 334000J/kg, how much energy is needed to melt the ice?Give your answer in MJ. Ensure your answer is quoted to the correct number of significant figures.

The heat of fusion for ice at 0 °C is 333.7 kJ/kg. What is the energy needed to melt 100 grams of ice at 0.00 °C?

A heater supplies 10.2 kJ of thermal energy is to heat 80 grams of ice at 0C. The specific latent heat of fusion of ice is 340 J/g. How much ice remains after heating?

50 g of ice at 0°C is added to 300 g of a liquid at 30°C. What will be the finaltemperature of the mixture when all the ice has melted? The specific heat capacity ofthe liquid is 265Jg-1°C-1 while that of water is 4 2 Jg-1°C-1.Specific latent heat of fusion of ice =336Jg-1 .[2]

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.
