It's easier for me to think about it as the gas being held at constant
pressure, such as with a weighted frictionless piston at the top of a
cylinder. Then when the gas is heated, the piston rises, doing mechanical
work without changing pressure.

KD, when the gas and container system radiates energy away, it cools,
unless an equal amount of energy is supplied to the system from outside
the system boundary.
