Incandescence is heat made visible – the process of turning heat energy into light energy. Our colloquial usage of "red hot," "white hot," and so on, is part of the color sequence black, red, orange, yellow, white, and bluish white, seen as an object is heated to successively higher temperatures.
Convection is the transfer of heat through the movement of large amounts of a liquid or gas. An example of this is the storm outside Paul’s cabin. Thunder and lightning are caused when a large mass of hot air meets a large mass of cool air. Warm air tends to rise, and cool air tends to fall. The movement of these air masses and the transfer of energy that occurs are called convection.
Rate of thermal energy transfer. We have learned that heat is the transfer of thermal energy from a high temperature location to a low temperature location. Temperature is the measure of the average kinetic energy of the particles of a substance. And the three methods of thermal energy transfer are conduction, convection, and radiation.
Heat is the transfer of thermal energy from a system to its surroundings or from one object to another as a result of a difference in temperature. Heat is measured in joules (J). This is because heat is a transfer of energy. Temperature is a measure of how hot or cold a substance feels and it is measured in degrees Celsius (°C).

HEAT TRANSFER T he spontaneous transfer of heat is always from warmer objects to cooler objects. If several objects near one another have dif-ferent temperatures, then those that are warm become cooler and those that are cool become warmer, until all have a common temperature. This equalization of temperatures is brought about in three ways:
The following are some of the most commonly used heat-transfer fluids and their properties. Consult a solar heating professional or the local authority having jurisdiction to determine the requirements for heat transfer fluid in solar water heating systems in your area.

This energy transfer is defined as heat. The three modes by which heat can be transferred from one place to another are conduction, convection and radiation. In conduction, heat is carried by means of collisions between rapidly moving molecules closer to the hot end of a body of matter and the slower molecules closer to the cold end.
