Answer 1

Here are the matches and short explanations:

Section 1 (vocabulary)
- Temperature — a measure of the average kinetic energy of the particles in a substance (how hot or cold something is; what a thermometer reads).
- Heat — thermal energy transferred from a warmer object to a cooler object because of a temperature difference.
- Energy — the ability to do work or cause change; can be stored or transferred in many forms.
- Thermal conductor — a material that transfers heat easily (e.g., metals).

Section 2 (forms of energy)
- Light Energy — energy carried by electromagnetic waves in the visible range (radiant energy).
- Chemical Energy — energy stored in chemical bonds that can be released in chemical reactions.
- Kinetic Energy — energy an object has because of its motion.
- Mechanical Energy — energy associated with the motion and position of an object (sum of kinetic and potential energy used to do work).
- Thermal Energy — the total kinetic energy of the particles in a substance (related to temperature and overall heat content).
- Electrical Energy — energy carried by moving electric charges.

Section 3 (modes of heat transfer)
- Radiation — transfer of energy by electromagnetic waves without needing a medium (example: warmth from the sun or a fire).
- Convection — transfer of heat by the bulk movement of fluids (liquids or gases) producing currents (example: boiling water circulation, warm air rising).
- Conduction — transfer of heat through direct contact between materials by particle collisions (example: a metal spoon getting hot in a pot).

Video true/false question
- "Wood, styrofoam, and paper are good conductors of heat." — False (they are poor conductors / good insulators).

Matching examples (typical pairings)
- Conduction — metal spoon in hot soup or a frying pan heating on a stove.
- Radiation — feeling the sun warming your skin or heat from a campfire without touching the flames.
- Convection — warm air rising from a heater, or convection currents in boiling water.
