Energy crossword puzzle

5. the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
7. a change from one state (solid or liquid or gas) to another without a change in chemical composition.
8. the internal energy of an object due to the kinetic energy of its atoms and/or molecules.
9. energy which a body possesses by virtue of being in motion
10. the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
14. power that an object gets from its position and motion.

1. the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
2. a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
3. an object or type of material that allows the flow of an electrical current in one or more directions.
4. a system primarily designed to supply energy-services to end-users.
5. a principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
6. the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.
11. the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
12. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
13. the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
