What happens to the thermal conductivity of a wall if its thickness is doubled?
Becomes double
remains the samewrong
Becomes halfcorrect
becomes one forth
It’s answer in the is wrong beacuse it remains same bacause it depends upon the nature of the object
As thermal conductivity is inversely proportional to length (thickness),so if thickness is doubled ,thermal conductivity will be halfed.This is according to formula of thermal conductivity.
Sir the MCQ
Water is a
Good conductor
Poor conductor ❎
Super conductor ✅
Insulator
Sir it’s answer is wrong because heat travels in water by conduction and convection and it is written on pg 198 in for your information
