### energy:

Heat energy
* More heat energy flows out of Jupiter and Saturn than they receive from the sun.
* Most heat energy becomes energy.
* Most heat energy causes molecular motion
* Most heat energy causes random molecular motion
  - drives steam turbines
  - heats water
  - produces coal
  - provides pressure
* Some heat energy becomes electrical energy input.
* Some heat energy comes from hot water
  - contains materials
  - depends on materials
  - generates metabolism
* Some heat energy is absorbed by water
  - released by fuel
* affects matter in various ways.
* can move through a substance by conduction
  - only be kinetic, since it is energy of moving particles
  - particles to move by simple definition
* comes in various forms and usually from a specific object or source.
* flows from regions.
* is almost always one of the products of energy transformations
  - also a type of radiant energy
  - an example of kinetic energy since heat is basically the movement of molecules
  - caused by the motion of particles that make up matter
  - directed by a change in the temperature
  - that is pushed into motion by using heat
  - in the disorderly motion of molecules
  - liberated as the reaction proceeds
  - produced by friction between the flowing water and the surface of the hill
* is released as the water vapor in the air condenses
  - in the condensation process
  - or absorbed as water changes state
  - stored in the floor to provide even warmth throughout the house for the whole day
* is the amount of energy in a substance
  - disorderly motion of molecules and in radiation
  - graveyard of all forms of energy
  - most easily lost or dissipated form of energy
  - transfered by the circulation of the air
  - transferred from hot places to cooler places by convection
* is transferred from the Earth's surface to the upper atmosphere
  - metal to the water
  - surface soil to the rocks below
  - warmer things to colder things
  - through the atmosphere as water changes from one state to another
  - transformed into radiand energy at ate surface of a heater
  - transmitted in Discussing the seven forms of energy
  - useful for doing many kinds of work
* raises the temperature of ocean water.
* serves purposes.
* travels from a warmer to a cooler location.

### energy | heat:

Additional heat
* is released when water freezes, thereby providing added cold protection.
* raises temperature.

### energy | heat:

Body heat
* Most body heat is lost through the head and neck regions
* Much body heat is lost through the head, where blood vessels are close to the surface.
* Some body heat is generated by metabolism.
* acts as a catalyst, pushing dampness far away from the body towards cooler, drier air.
* damages Rips over time.
* is carried away by air currents
  - films
  - generated by the metabolic activity of every cell
* is lost by the following four mechanisms
  - through damp clothing by evaporation
  - when the dead air spaces in clothing are subjected to the effects of wind
  - part of chaos
  - produced by metabolic activity and shivering
  - trapped between the hair fibers providing a layer of insulation from the environment
* speeds the release of aromatic vapors of the oils.

Central heating
* eats up energy.
* is heat
  - heating systems
* is payable on consumption together with electricity
  - fireplace wood
  - wood for the fireplace
  - with gas and gas is payable on consumption during heating season
* provides a warm environment conducive to the survival of termites during winter.

Damp heat
* explains many urogenital infections.
* is an energetic condition of the body that is just what it sounds like.

Dry heat
* can dry out a cat's or dog's coat and skin.
* is best for cuts of meat that are naturally tender
  - very slow in penetrating into jars of food
