A heat engine takes in 1120 J of heat from the hot reservoir and exhausts 700 J of heat to the cold reservoir. How much work is done by the engine?

increase masses, decrease separation

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
