Study the given diagram carefully. Candle wax was coated at different parts P, Q, R and S of the metal rod. Which one of the following is the correct order in which the wax would melt?
AP, Q, R, S
BS, R, Q, P
CR, Q, P, S
DR, Q, S, P
D
Ans 2:
Class : Class 6
The correct answer is D because R is closest to the candle so S will melt first. Then Q is the second closest so it will it melt after R. S is the third closest to the candle as you can see it carefully. The distance between P and Q and R and S is same but the candle is more closer to R so S would melt after Q.
