What is the generated entropy (in kJ/K) when 1 kg of liquid water at 25°C is heated to saturated vapor at 100°C in an oven that is at 150°C. Hint: the effect of pressure on the entropy of liquids or solids is usually negligible. Now assume you are trying to heat 1 kg of liquid water at 25°C to saturated vapor at 100°C, but you want to do it in an oven that is at 80°C. This is obviously impossible...

Neon gas is heated from 298 K (1 atm pressure) to 500 K under the following conditions: (a) at constant volume; (b) at constant pressure. In each case, find the molar entropy of the gas in its final state (at 500 K) given that its standard molar entropy at 298 K is 146.33 J/mol K. Assume that neon is ideal gas.

When the pressure P is constant at 1 atm, the melting point of Br_2 is T_m = 265.95 K and its boiling point is T_b = 331.85 K. Br_2 is therefore liquid at 298 K and 1 atm but it also has a finite vapor pressure hence the property of both liquid and gas Br_2 can be obtained at at 298 K and 1 atm. Using a DeHoff equation and the thermodynamic table on D2L calculate the absolute molar entropy...
