Conduction: the transfer of thermal energy between objects in direct contact with each other
Convection: the transfer of thermal energy through currents in liquids and gases
Radiation: the transfer of thermal energy from a light source (e.g., Sun, fire, light bulb, and burner) to an object or a substance
Thermal Energy: heat energy
Thermal Equilibrium: two substances in the same system exchange no thermal energy and are at the same temperature

Energy Transfer: he process where energy changes from one form to another, or moves from one place to another, always following the principle of conservation of energy
Kinetic energy: a form of energy that an object or a particle has by reason of its motion
Medium: a substance that moves energy or light from one place to another
Molecule: a group of two or more atoms that are held together by attractive forces known as chemical bonds
System: a set of principles or procedures according to which something is done; an organized framework or method.
Temperature: 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.
Mini Lessons
How Does thermal energy transfer through systems?
how are they related?
7.8: Force, motion, and energy. The student understands the behavior of thermal energy as it flows into and out of systems. The student is expected to:
7.8.A: investigate methods of thermal energy transfer into and out of systems, including conduction, convection, and radiation;
7.8.B: investigate how thermal energy moves in a predictable pattern from warmer to cooler until all substances within the system reach thermal equilibrium; and
7.8.C: explain the relationship between temperature and the kinetic energy of the particles within a substance
