Returning to the scene of the (possible) crime, you estimate that the bathtub in which polly was found contained around 0.3 m3 (around 80 gallons), which corresponds to 300 kg (since the density of water is 1000 kg/m3), of water as you scoop the water out of the tub. the temperature of this water is 7oc. you assume that the water was initially at its lowest temperature, 2oc, which you find by turning on the cold tap only. with these measurements, first determine the amount of heat that transferred from polly and the external environment to warm the cold water. the specific heat of water is about 4186 j/(kgoc). give your answers in units of kilojoules (kj).
