A copper block at 100 °C is placed into thermal contact with a copper block at 10 °C. They equilibrate to 55 °C. Both have heat capacity of 150 J K. Calculate AStot (JK). Do not include units in your answer. Nrite the numerical value in normal form. QUESTION 7 Water (1 kg) at 20 °C is placed in contact with a 50 °C reservoir. After it equilibrates, it is placed in contact with a 100 °C reservoir until it equilibrates. Calculate AStot (in kJ K, note units) of the process. Let Cwater = 4.2 kJ/kg-K. Do not include units in your answer. Write the numerical value in normal form. AILAnc werr
