1. What is the core process?A heat transfer operation that raises water temperature using an energy input
2. What is the primary applications?Domestic uses (cooking, cleaning, bathing, space heating) and industrial processes
3. How do electric water heaters make water hot?Electric water heaters use electricity to heat a metal element inside the water, and the heat from that element warms the water around it.
4. Why is hot water important for cleaning and health?Hot water helps remove germs and dirt better than cold water, making bathing, handwashing, and food preparation safer.

Thermodynamics: The branch of physics dealing with heat and its relation to other forms of energy and work.
Heat Exchanger: A device designed to efficiently transfer heat from one fluid to another without direct contact.
Combined Heat and Power (CHP): A process that generates both electricity and useful heat from a single fuel source.
Energy Efficiency Ratio (EER): A measure of how efficiently an appliance uses energy, particularly relevant for heat pumps.
