Document Summary
Quiz 09 (unnnounced) 151102 dr. maris. Instructions: show all work and state all assumptions. Incomplete work (even with correct numeric answers) will not receive full credit: no internet assisted devices of any kind including cell phones, smart watches. Use of such devices will result in a zero grade. A kilogram of benzene at its melting point of 5. 53 c is added to 5 kg of benzene at 50 c and 1 bar. The enthalpy of melting of benzene is 127. 4 kj/kg. If the process is adiabatic, calculate: the final equilibrium temperature. Justify your answer to each question by providing clear and concise responses. Solution: we are given that cold" benzene (tc = 5. 53 c) is added to hot" benzene (th = 50 c): the entropy generated in the process. Heat will transfer from the hot benzene to the cold benzene until they both reach the same temperature (tfinal).
