You work in a materials testing lab and your boss tells you to increase the temperature of a sample by 47.1 "C. The only thermometer you can find at your workbench reads in degrees Fahrenheit. Part A If the initial temperature of the sample is 62.1 F, what is its temperature in degrees Fahrenheit when the desired temperature increase has been achieved? Express your answer in degrees Fahrenheit to three significant figures. View Available Hint(s) VO ? TF = Submit700 J of heat energy are transferred to a system that does 400 J of work. Part A By how much does the system's thermal energy change? Express your answer in joules. DA ? AEth = J Submit Request AnswerSix new prototypes for internal-combustion engines are tested in the laboratory. For each engine, the heat energy input and output per cycle, and the designed number of cycles per second are measured. Part A Rank these engines on the basis of the work they perform per cycle. Rank from largest to smallest. To rank items as equivalent, overlap them. > View Available Hint(s) Qin = 3000 J Qin = 2000 J Qin = 1000 J Qout = 1500 J Qin = 2000 J Qout = 500 J Qin = 4000 J Qout = 200 J Qin = 1500 J Qout = 1000 J f = 150 Hz Qout = 3000 J f = 50 Hz Qout = 500 J f = 200 Hz f = 100 Hz f = 50 Hz f = 200 Hz
