  1. 2. 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 the transfer of heat.
  2. 5. a state in which opposing forces or influences are balanced.
  3. 6. The strength and vitality required for sustained physical or mental activity, power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
  4. 7. an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol which extends along the tube as it expands.
  5. 8. relating to the movement towards a centre of gravity.
  6. 10. the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
  7. 11. the quantity determining the energy of mass in a gravitational field or of charge in an electric field.
  8. 13. cord, tape, or fabric, woven with strips of rubber, which returns to its original length or shape after being stretched.
  9. 14. relating to chemistry, or the interactions of substances as studied in chemistry, a distinct compound or substance, especially one which has been artificially prepared or purified.

  1. 1. a process in which energy is used or lost without accomplishing useful work, as friction causing loss of mechanical energy.
  2. 3. 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.
  3. 4. relating to or resulting from motion.
  4. 9. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
  5. 12. Also, thermic. of, relating to, or caused by heat or temperature.
  6. 16. the capture of energy produced at one time for use at a later time. A device that ______ energy is sometimes called an accumulator. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic.
