A sample of graphite (C,-0.720) with a mass of 10.9 g is initially at a temperature of 52.3°C. The sample is cooled by removing 39.6 J of energy. Calculate the final temperature (in °C) of this sample. Assume no phase changes occur and that the specific heat capacity does not vary with temperature. Report your answer to 3 significant figures without the unit. Example: 10.0 Type your answer... A sample of aluminum (C, -0.900) with a mass of 10.8 g is initially at a temperature of 57.8 °C. The sample is heated by adding 38.3 J of energy. Calculate the final temperature (in °C) of this sample. Assume no phase changes occur and that the specific heat capacity does not vary with temperature. Report your answer to 3 significant figures without the unit. Example: 10.0 Type your answer...
