Questions 1.What is adiabatic operation? 2.What is heat exchanger? 3.What is Condenser? 4.What is Boiler? 5.What is latent heat? 6.What is sensible heat? 7.What is reactor? Answers: 1.An adiabatic process occurs without transferring heat or mass between a thermodynamic system and its surroundings. 2.A heat exchanger is a system used to transfer heat between two or more fluids. 3.A condenser unit used in central air conditioning systems typically has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid 4.A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. 5.The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure 6. It is the energy moving from one system to another that changes the temperature rather than changing its phase 7.A chemical reactor is an enclosed volume in which a chemical reaction takes place. In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction.
