Explanation:
The discharged vapor picks up additional sources of sensible heat through the processes of conduction and convection. Conduction is the transfer of heat between two objects in direct contact with each other. When the discharged vapor comes into contact with a hotter object, heat is transferred from the hotter object to the vapor, causing the vapor to gain sensible heat. On the other hand, convection is heat transfer by the movement of mass. As the discharged vapor moves or circulates in a medium (such as air or a liquid), it picks up heat from the hotter parts of the medium, thereby also gaining sensible heat.
