Question
Specific Heat Capacity of substance A is 3.8 J g-1 K-1 whereas the specific heat capacity of substance B is 0.4 J g-1 K T-1.
i) Which of the two is a good conductor of heat?
ii) How is one led to the above conclusion?
iii) If substances A and B are liquids then which one would be more useful in car radiators?
Solution
i) Substance B is a good conductor of heat. Less is the specific heat capacity of a substance, the better it acts as a good conductor. Less specific heat means it takes little heat for heat transfer.
ii)Since, specific heat capacity of B is less than that of A, B is a good conductor.
iii) Substance A is more useful in car radiator.
