← A drop of water of radius 1.0 mm is sprayed into 1000 identical tiny droplets. The surface tension of water is 0.072 N/m. Ignoring any change in temperature, the work needed to do this is closest toA gas is taken from state A to state B along two different paths, shown in the pressure-volume diagram. Along path ACB it absorbs 80 J of heat and does 30 J of work. Along path ADB it does 10 J of work. Later the gas is brought back from B to A along the curved path, and 20 J of work is done on the gas on the way. Which statement is correct? →
