Fill in each blank with the correct word from the lesson.

1. Electric wires use _______ to conduct electricity and heat, wrapped in plastic insulation to prevent shocks.
2. _______ is the transfer of heat through a material by direct contact, without the material itself moving.
3. Good conductors include metals like copper, _______, and aluminium.
4. Metals are ex_______ent conductors because they have free electrons that carry energy rapidly.
5. Winter clothes trap air between _______s — air is a poor conductor, so body heat is not lost quickly.

Choose the best option for each question.

1. Why do metals feel colder than wood at the same temperature?
   a) Metals are always at a lower temperatureb) Metals conduct heat away from your skin fasterc) Wood absorbs more heatd) Metals have no particles
2. Which of these is the best conductor of heat?
   a) Woodb) Plasticc) Rubberd) Copper
3. What is conduction?
   a) Heat transfer through moving fluidsb) Heat transfer through empty spacec) Heat transfer through direct particle contactd) Heat transfer through light

Write T for True or F for False in the brackets.

1. Metals conduct heat away from your skin faster is one of the key concepts in the lesson on Heat Transfer: Conduction.
2. Metals are always at a lower temperature is the main topic of this lesson.
3. Electric wires use copper to conduct electricity and heat, wrapped in plastic insulation to prevent shocks.
4. Electric wires use Wood to conduct electricity and heat, wrapped in plastic insulation to prevent shocks.
