photo credit: Kmecfiunit Key Ideas from Lessons:  Heat is transferred through matter in three different ways: conduction, convection, and radiation. Conduction occurs when two objects of different temperatures are in direct contact with each other and heat is transferred from molecule to molecule. Radiation is the transfer of thermal energy that does not require contact or the presence of any matter between the heat source and the object being heated. Convection is the transfer of heat by the movement of currents in a fluid (a gas or a liquid). As a … Read More

Key Ideas from the Lessons: (Source: http://assessment.aaas.org/topics) Thermal energy is the total kinetic energy (energy of motion) of all the particles in an object. Heated molecules have a lot of kinetic energy and thus move a lot while cold molecules do not have as much thermal energy … Read More
