A heat transfer process results in 17 kilocalories of heat being removed from one liter (1 kilogram) of water. What temperature will the water be if it started at a temperature of 25°C?
A) 1 kilogram / 17 kilocalories = 0.059°C ?T 25°C - 0.059°C = 24.041°C B) 17 kilocalories - 1 kilogram = 16°C ?T 25°C + 16°C = 41°C C) 17 kilocalories/1 kilogram = 17°C ?T 25°C + 17°C = 42°C D) 17 kilocalories/1 kilogram = 17°C ?T 25°C - 17°C = 8°C
