Section A (50 marks) consists of the structure-type questions, and Section B (20 marks) consists of multiple choice questions. Section A (50 marks) 1.

(ii) a cup of significant heat capacity is used. (iii) the remaining ice is taken out from the cup before thermal equilibrium is reached. 3
4 4. The figure shows the internal structure of an electrical appliance. Wet air flows into Part A of the appliance and dry air flows out from Part B of it. A liquid called the refrigerant circulates through the coiled tube. The refrigerant absorbs heat from the wet air and evaporates inside the coiled tube in Part A. The vapour of the refrigerant is then pumped to the coiled tube in Part B where it is compressed and condensed into a liquid. The liquid refrigerant then passes back to the coiled tube in Part A and the process is repeated. Wet air in Coiled tube Water tank Part A Air fan Part B Metal fins pump (a) Suggest the electrical appliance in which the above structure can apply. (1 mark) Dry air out (b) In the coil tube in Part A, the refrigerant absorbs heat to evaporate into vapour. State the change of average potential energy of the refrigerant molecules during the process of changing state. (1 mark) (c) Explain why the coiled tube in Part A is designed in a coiled shape. (d) In the coiled tube in Part B, the vapour of the refrigerant is compressed and condenses into liquid. Explain, in terms of molecular motion, why the coiled tube in Part B gives out heat. (e) State and explain two designs that could prevent the Part B from overheating. (f) Suppose water vapour in the incoming wet air condenses and 1.8 kg of water is collected in the water tank. (i) Estimate the total energy released by the water vapour. The specific latent heat of vaporization of water is J kg -1. (ii) Using the data and the formula in the following table, estimate the increase in temperature of the air in the room, assuming that all energy released in Part B is used to raise the temperature of air inside the room. Volume of the air in the room = 400 m 3 Density of the air = 1.3 kg m -3 Specific heat capacity of air = 1030 J kg -1 o C -1 Mass = density volume End of Section A 4
