Question

30. Example 19.40: A cylinder holds n mol of compressed gas at temperature T. It's connected by a hose of negligible volume to an identical cylinder that's been pumped down to vacuum. When the valve on the full cylinder is opened, the gas expands to fill the entire system while maintaining the constant temperature T. Find an expression for the energy that becomes unavailable to do work as a result of this process.
