q8

Part A A typical student listening attentively to a physics lecture has a heat output of 103 W. How much heat energy does a class of 90 physics students release into a lecture hall over the course of a 50 min lecture? Express your answer in joules. Q = Submit Request Answer Part B Assume that all the heat energy in part A is transferred to the 3198 m" of air in the room. The air has a specific heat of 1020 J/(kg . K) and a density of 1.20 kg/mo. If none of the heat escapes and the air-conditioning system is off, how much will the temperature of the air in the room rise during the 50 min lecture? Express your answer in Celsius degrees. 1VO AEd AT: Submit Request Answer Part C If the class is taking an exam, the heat output per student rises to 285 W. What is the temperature rise during 50 min in this case? Express your answer in Celsius degrees. AEd AT: Submit Request Answer Return to Assignment Provide Feedback Pearson
