A 2.0 kg sample of water exists initially as a liquid at 20°C and converts to a water vapor as it heats up to 150 °C in a very large room. The room is at 350 K temperature and 101,325 Pa pressure. Prove (with calculations) whether this process will occur spontaneously. Assume water vapor acts as a poly-atomic ideal gas and that liquid water is incompressible and experiences no thermal expansion. Mwater = 0.018 kg/mol Liquid Water: C = 4187...
