Across
  1. 4. Heat, the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
  2. 6. 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.
  3. 8. Energy, the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
  4. 10. 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.
  5. 12. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
  6. 13. a person who directs the performance of an orchestra or choir.
  7. 14. System, An energy system is a system primarily designed to supply energy-services to end-users.
  8. 15. Energy, Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.
Down
  1. 1. Energy, energy which a body possesses by virtue of being in motion.
  2. 2. 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 the transfer of heat.
  3. 3. Change, Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.
  4. 5. Energy, Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
  5. 7. of Energy, a principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
  6. 9. 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.
  7. 11. a substance which does not readily allow the passage of heat or sound.
