Humid air at 100 kPa, 30°C, and 90% relative humidity is compressed to 300 kPa in an internally reversible isothermal process in a cylinder–piston assembly while interacting with a reservoir at 10°C.

a. Find the relative humidity after the compression.

 b. Find the work and heat interactions.

 c. Determine the irreversibility relative to an environment at 100 kPa and 27°C.
