- 3. In the context of energy, it refers to the principle that energy cannot be created or destroyed, only transformed from one form to another.
- 9. Also known as thermal energy, it is the energy that comes from the movement of atoms and molecules in a substance.
- 10. Energy caused by the movement of electrons. It is commonly used to power devices and appliances.
- 11. The process of changing energy from one form to another, such as chemical energy to thermal energy.
- 12. Energy that travels through substances in waves caused by vibrations.
- 13. Energy stored in the bonds of atoms and molecules. It is released during chemical reactions, such as burning fuel.
Down
- 1. A fundamental principle stating that the total energy in a closed system remains constant, though it can change forms.
- 2. Energy that travels in waves and can move through empty space. It is a type of electromagnetic energy.
- 4. The sum of kinetic and potential energy in an object that is used to do work. Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.
- 5. A measure of the average kinetic energy of the particles in a substance. It determines how hot or cold the substance is.
- 6. A set of interacting or interdependent components forming an integrated whole. In science, it often refers to a specific part of the universe being studied.
- 7. A state where opposing forces or influences are balanced. In terms of heat, it is when two objects reach the same temperature and heat transfer stops.
- 8. The transfer of thermal energy from a warmer object to a cooler one.
