The final temperature of the water and melted ice is 0 ºC. No heat is lost to, or gained from, the surroundings and the ice completely melted. The specific heat capacity of water is 4.2 J/(g ºC). What is the specific latent heat of ice? 341 J/g 4700 J/g 12 600 J/g 47 J/g 2 / 5 2) A slice of bread is placed under a red-hot electric grill to make toast. How does heat energy reach the bread? Convection and radiation Conduction only Radiation only Conduction and convection 3 / 5 3) Two solid substances U and V are heated by the same heater. The graph below shows the variation of temperature with time for these substances. If U and V have the same mass, which of the following statements must be true? Liquid U has a lower specific heat capacity than liquid V. The specific latent heat of fusion of U is higher than that of V. The melting point of U is higher than V. Solid U has a higher specific heat capacity than solid V. 4 / 5 4) 2021 S4 EOY P1 Q30 40 000 J of thermal energy is added to 1.0 kg of ice at –10 ºC. specific heat capacity of ice, = 2090 J (kg K)⁻¹ specific latent heat of fusion of ice, = 3.34 x 105J kg⁻¹ What is the mass of ice that melts assuming there is no energy loss to the surroundings? 0.057 kg 0.11 kg 0.011 kg 1.0 kg 5 / 5 5) A fixed mass of gas expands at constant temperature in a syringe.
