- 3. The branch of physical science that deals with the relations between heat and other forms of energy
- 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
- 7. A substance which does not readily allow the passage of heat or sound
- 8. A principle stating that energy cannot be created or destroyed, but can be altered from one form to another
- 9. Internal energy of an object due to the kinetic energy of its atoms and/or molecules
- 10. 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
- 12. Designed to supply energy-services to end-users
