(a) and (b) are not related. (a) A 0.200 m3 electric water heater uses 3.00 kW. Assuming no heat loss, how many hours would it take to heat the water in this tank from 23.0∘C to 75.0∘C ? The specific heat of water is 4186 J kg−1 K−1 and its density is 1000 kg m−3. (2 marks) (b) A 40.0 g block of ice at −15.00∘C is dropped into a calorimeter (of negligible heat capacity) containing water at 15.00∘C. When equilibrium is reached, the final temperature is 8.00∘C. How much water did the calorimeter contain initially? The specific heat of ice is 2090 J kg−1 K−1; The specific heat of water is 4186 J kg−1 K−1. The latent heat of fusion of water is 33.5×104 Jkg−1 (3 marks)
