Energy

2. The transfer of energy in the form of electromagnetic waves, like heat from the sun or microwaves in a microwave oven.
6. The measure of how well energy is converted from one form to another, usually expressed as a percentage.
8. The transfer of heat energy in a fluid (liquid or gas) through the movement of the fluid itself, creating currents that distribute heat.
11. The process of changing energy from one form to another, such as from potential energy to kinetic energy.

1. The principle that states energy cannot be created or destroyed, only transferred or converted from one form to another.
3. In the context of energy, it refers to the energy that is lost or not used efficiently during a process or conversion.
4. A closed loop or pathway through which electricity can flow, allowing it to power devices or perform work.
5. A form of energy resulting from the movement of charged particles, typically electrons, through conductive materials.
7. Energy that is stored in an object due to its position or condition, which has the potential to do work in the future.
9. The ability to do work or cause a change.
10. The energy an object possesses due to its motion.
