bhakta (ssb778) – Homework 6: Thermodynamics II – Shear – (52375) 1 This print-out should have 12 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. DrRuth says: here are some useful conver- sion factors and constants: R = 8.314 J/mol K; 1 L atm = 101.325 J; 1 cal = 4.184 J. Also, remember that internal energy is E in our textbook, but some older textbooks, and some Quest questions, use U instead of E. Be careful of units. S is usually J/K mol and Delta H is usually kJ/mol. Notice the differ- ence between J and kJ. 001 10.0 points A system had 150 kJ of work done on it andits internal energy increased by 60 kJ. Howmuch energy did the system gain or lose asheat? 1.The system lost 90 kJ of energy as heat.2.The system lost 210 kJ of energy as heat.3.The system gained 90 kJ of energy asheat. 4. The system gained 210 kJ of energy as heat. 5. The system gained 60 kJ of energy as heat. 002 10.0 points
