Physics
In the physics laboratory, various blocks of materials labelled A and B, each with masses ranging from 10 grams to 50 grams, are utilised to determine their respective heat capacities. Subsequently, a graph is plotted to depict the relationship between the heat capacity and the mass of the materials, as shown.
(a) Plot a graph illustrating the relationship between the mass and specific heat capacity of materials A and B.
(b) Which material is a relatively better conductor?

Answer
(a)
(b) B
Explanation:
Generally, materials with lower specific heat capacity heat up more quickly when thermal energy is applied. Hence, Material B, with the lower specific heat capacity, would be a better thermal conductor.
