🔍 Key Concepts

• Latent heat vs. sensible heat – what changes during a phase change (liquid to vapor) vs. what changes during a temperature rise with no phase change • In an evaporator/heat exchanger, which side usually undergoes a phase change (boiling/evaporation) and which stays liquid with only temperature change? • How engine jacket water normally behaves in cooling systems (what kind of heat it carries from the engine)

💭 Think About

• When sea water is being evaporated, is its temperature rising without boiling, or is it changing phase from liquid to vapor? Which type of heat is mainly involved in that process? • The diesel engine jacket water is already hot from cooling the engine. As it gives up heat in the heat exchanger, does it condense/evaporate (phase change) or simply cool down (temperature drop only)? • Match each choice to: (1) sea water: phase change or just warming? (2) jacket water: phase change or just cooling? Then decide which one involves latent vs sensible heat.

✅ Before You Answer

• Be clear on the definition: latent heat = heat absorbed/released during phase change at (nearly) constant temperature • Be clear on the definition: sensible heat = heat that causes a temperature change without phase change • Check which fluid in this setup actually changes phase and which fluid stays liquid while transferring heat.
