1)A gas is compressed at a constant pressure of 0.800 atm from 8.00 L to 1.00 L. In the process, 410 J of energy leaves the gas by heat. (a) What is the work done on the gas? J (b) What is the change in its internal energy? J 2) A gas increases in pressure from 2.00 atm to 6.00 atm at a constant volume of 1.00 m3 and then expands at constant pressure to a volume of 3.00 m3...
In one cycle, a heat engine absorbs 520 J from a high-temperature reservoir and expels 310 J to a low-temperature reservoir. If the efficiency of this engine is 59% of the efficiency of a Carnot engine, what is the ratio of the low temperature to the high temperature in the Carnot engine?
