7.24 One kg of air in a piston-cylinder assembly, initially at 1 bar and 25°C, is heated at constant pressure with no internal irreversibilities to a final temperature of 177°C. Employing the ideal gas model, determine the work, the heat transfer, and the amounts of exergy transfer accompanying work and heat transfer, each in kJ. Let To = 298 K, po 1 bar and ignore the effects of motion and gravity. =
