Across
- 3. Power is derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
- 4. Energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by product (exothermic reaction). Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.
- 6. A renewable energy source that harnesses the power of wind currents. Usually uses turbines to generate electricity.
- 11. Process by which, in a fluid being heated, the warmer part of the mass will rise and the cooler portions will sink.
- 12. A law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.
- 13. Energy from the sun that is converted into thermal or electrical energy
- 14. Energy that is radiated or transmitted in the form of rays or waves or particles.
- 16. The energy that is stored and held in readiness
- 18. The process of changing one form of energy to one other. In physics, the term energy describes the capacity to produce certain changes within any system, without regard to limitations in transformation imposed.
- 20. A measure of the total dry mass of organisms within a particular region
Down
- 1. The internal energy of an object due to the kinetic energy of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion.
- 2. Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.
- 5. The energy that an object has due to its motion
- 7. The potential energy stored in the nucleus of the atom. it is released during atomic fission.
- 8. The sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.
- 9. The result when a force, either sound or pressure, makes an object or substance vibrate.
- 10. A form of energy that is transferred by a difference in temperature.
- 15. The SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
- 17. the potential energy a massive object has in relation to another massive object due to gravity.
- 19. The energy caused by the movement of electrons.
