It is a good conductor of heat (to cook food) and not flexible (keeps its shape). [1]
17. (a) Beaker A (metal spoon) [1]
(b) Metal is a good conductor of heat. Heat from the hot water travels quickly through the metal spoon to the butter, causing it to melt first. [2]
(c) Thermal conductivity (or "good conductor of heat") [1]
(d) Any one of the following: [1]
- Same volume and temperature of hot water in each beaker
- Same size and initial temperature of butter pats

- Same distance of butter from water level
(e) Type of material of the spoon (metal, wood, plastic) [1]
18. (a) Container A (metal) [1]
(b) Metal is a good conductor of heat. It conducts heat away from the hot water to the surroundings the fastest, causing the water to cool down the fastest. [2]
(c) Any one of the following: [1]

- Same initial temperature of water (80°C)
- Same size and shape of containers
- Same surrounding temperature

(d) Copper is non-magnetic (not attracted to a magnet) / Copper is a good conductor of heat and electricity. [1]
(e) Plastic is non-magnetic / Plastic is flexible / Plastic is an insulator (poor conductor of heat and electricity). [1]
20. (a) The metal spoon will conduct heat at the same speed in all three beakers (A, B, and C). [1]
(b) The spoon is identical (same material, size, shape) in all three beakers. The property of the spoon (thermal conductivity) does not change. The liquids only affect how quickly heat is transferred from the water to the spoon, but the question asks how fast the spoon conducts heat (along its length). [2]
Alternative acceptable answer if interpreted as "which liquid transfers heat to the spoon fastest":
Beaker A (water) - Water has the highest thermal conductivity among the three liquids, so it transfers heat to the spoon fastest. [2]
(c) Any one of the following: [1]
- Identical metal spoons (same material, size, shape)
- Same volume of liquid (100 ml)
- Same initial temperature of liquids (room temperature)
- Same beakers
- Same temperature of hot water poured in
(d) Type of liquid (water, cooking oil, honey) [1]
(e) Thermal conductivity of the liquids (or "how well different liquids conduct heat") [1]
