What happens to refrigerant pressure as it leaves the compressor?

The compressor’s job is to raise the pressure (and temperature) of the refrigerant vapor it receives from the evaporator. Since the refrigerant leaves the evaporator as low-pressure vapor, the compressor increases that pressure, producing high-pressure vapor that then moves to the condenser. It’s this high-pressure, hot gas leaving the compressor that drives the rest of the cycle and later condenses into high-pressure liquid in the condenser.
