A science teacher labelled three glass slides as P, Q and R. She painted slide Q with light blue colour, slide R with black colour and slide P was left as such. Then she asked students to put the slide on a white paper having X mark on it. Students will be able to see the mark clearly (or partially):
Depending upon the nature of the constituents present in a mixture, Suhana, a class student suggested some methods of separation as shown in the table.
| Types of mixture | Methods of separation | |
|---|---|---|
| Solid — Solid | Handpicking, Sieving | |
| Solid —Liquid (insoluble) | Sedimentation — Decantation, Filtration | |
| Liquid — Liquid (immiscible) | Decantation, Separating funnel | |
| Solid — Liquid (soluble) | Filtration, Decantation | |
| Liquid — Liquid (miscible) | Distillation |
Study the given flow chart carefully.
P, Q and R could be respectively:
Four rods of equal length and thickness but of different materials are coated with wax in the same manner. They are fixed to a trough containing hot water. The given diagram illustrates what happens to the wax on each rod after five minutes.
What can you conclude from the given diagram?
(i) The aluminium rod conducts heat better than the brass rod.
(ii) The aluminium rod conducts heat better than the copper rod.
(iii) The glass rod conducts heat better than the copper rod.
(iv) The wax on the copper rod melts faster than the wax on the brass rod.
