True or False: The vapor leaving the compressor is at a higher pressure than the vapor entering.

Explanation:
In operation, the compressor does work on the refrigerant vapor to raise its pressure (and temperature). The gas leaving the compressor is at a higher pressure than the vapor entering, which is necessary to push the refrigerant through the condenser where it will reject heat and condense. So the statement is true. In normal operation there isn’t a scenario where the discharge pressure isn’t higher than the suction pressure, though pressures can vary with load or faults.
