Heat is transferred through conduction, convection, and radiation - Conduction is the transfer of heat from one part to another within an object or between objects by direct contact. - Convection is the transfer of heat from one region to another by the movement of fluids. - Radiation is the release of heat from the surface of most bodies that is transferred directly from one region to another. 4. What is refraction? The bending of lght at the boundary of the two media. 5. Why the refraction occurs? Refraction occurs because the speed of light changes as it enters a different medium. 6. What are the component of electric cir
