2PRACTICE PROBLEM
A chef wants to reduce the cooking time by a few minutes. To succeed, he raises the pressure to 4 atm inside the cooker. At this pressure, the boiling point of water, the density of water, and the density of steam are 144 °C, 922.2 kg/m3, and 2.163 kg/m3 respectively. What is the work (W) done by 200 g of steam formed at 144 °C inside the cooker?
