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. |
A) (i) and (iv)
B) (ii) and (iii)
C) (i), (ii) and (iii)
D) (ii), (iii) and (iv)
Correct Answer: A
Solution :
By observing the amount of wax melted in each case in the figure, we can conclude about the conductivity of the rods. As the wax melted maximum on copper rod, it is a good conductor of heat followed by aluminium and brass. Glass is an insulator.You need to login to perform this action.
