QUESTION 6 A piece of unknown material weighs 0.4 kg. It is heated to 70 °C, then transferred into a 2 kg bath of oil at 20 °C. The bath temperature eventually reaches 40 °C. Assuming that Cmaterial = 0.6 kJ/(kg-K), calculate the heat in kJ that it lost when placed in contact with the oil. In this case, consider the amount of heat lost to be a positive quantity. Do not include units in your answer and write the numerical value in normal form. %3D QUESTION 7 This problem is concerned with the same situation as the previous problem. A piece of unknown material weighs 0.4 kg. It is heated to 70 °C, then transferred into a 2 kg bath of oil at 20 °C. The bath temperature eventually reaches 40 °C. Assuming that Cmaterial = 0.6 kJ/(kg-K), calculate the heat energy in kJ gained by the oil. Do not include units in your answer and write the numerical value in normal form.
