The image below shows a pool with 1.8 t of water coupled to a solar heater. Due to its influence, at 7:00 am, the water in this pool was at 10"C, even with the environment at 6"C. During the following hour, the pool water remained 4 C above ambient temperature and the heat absorbed by the water surface from solar radiation was equal to the heat lost by conduction to the air by that same surface. Aquecedor solar The walls and bottom of the pool were made of polystyrene, were 2 cm thick and 7 m of total area. At 8:00 am, the pool water reached a temperature of 14*C. from 7:00 am to 8:00 am, what is the power associated with the supply of heat from the heater to the pool water, ignoring the mass of water that is in the tubes and in the heater? Data: specific heat of water = 4 kJ/kg"C Thermal conductivity of polystyrene = 0.04 W/m."c a) 64 W b) 72 W c) 58 W d) 68 W e) 76 W
