Questions 16-19 refer to a cup which contains water at room temperature. The cup is perfectly insulated so that no heat can transfer into or out of the cup. A small coffee cup heater inside the cup is used to transfer heat to the water. The water does not boil. If heat is transferred to the cup at a steady rate, which of the graphs below best represents the shape of the graph of the temperature of the water over time as the heat is transferred? Each of the questions 17-19 describes a change in the situation described in question 16 (a heater in water in a perfectly insulated cup). For each question, choose the answer that best describes the temperature rise due to the change described. The temperature rise would be There is the same amount of water and twice the amount of heat is transferred. There is half as much water and the same amount of heat is transferred. The water is replaced by an equal mass of a liquid with half the specific heat capacity of water. The same amount of heat is transferred.Explanation / Answer
