Randall D. Knight — Work, Heat, and the First Law of Thermodynamics: Problem 9

The gas cylinder in FIGURE Q19.9 is a rigid container that is well insulated except for the bottom surface, which is in contact with a block of ice. The initial gas temperature is \( T > 0^\circ\text{C} \). a. During the process that occurs until the gas reaches a new equilibrium, are (i) \( \Delta T \), (ii) \( W \), and (iii) \( Q \) greater than, less than, or equal to zero? Explain. b. Draw a \( pV \) diagram showing the process.
