Review Heat, light, and electricity before starting →Ideas to recall
- Temperature measures average molecular kinetic energy; heat is thermal energy flowing across a temperature gradient.
- Thermal energy transfers via solid conduction, fluid convection, or vacuum-permeating electromagnetic radiation.
- Light refracts when transitioning between media because its propagation velocity alters ($v = c/n$).
- Current requires a complete conductive circuit; series circuits share a common current, while parallel circuits maintain equal branch voltages.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
