would use to solve each of the problems. Use no more than 100 words for each section. Each section is worth 10 marks giving a total of 20 marks for the question. An adult mammalian cell of mass 1.2 nanograms absorbs a flow of glucose that is broken down to produce 3.5x10-10W of energy plus carbon dioxide and water which over a 30 second period cause the cell to expand against a pressure 101,325 Pa by3200um3 and its temperature to rise from 36.6°C by 0.15°C. Given that the specific heat capacity of the cell is 4.184 J/g.K, how much heat will the cell need to transfer to its surroundings to return its temperature to 36.6°C? ) In a shower-room of floor dimensions 2m by 5m with a 2.5m high ceiling, a 2kW electricshower is left running for 6 minutes at 0.2 litres/second. The heat loss from thesurfaces of the room is 55W and during the six minutes its temperature rises 12°C from20°C. What is the specific enthalpy change of the water, given a height differencebetween the showerhead and the drain of 2.2m?
