Vijay performed an experiment to compare the heat conductivity of four different materials P, Q, R and S. Thumbtacks were fixed with wax on each material and then the materials were fixed to a trough containing hot water as shown in the diagram. Vijay tabulated his results as shown here. MaterialTime taken for thumbtacks to drop (minutes)P5Q6R2S4What can be inferred from his experiment?
