Question:-
Assertion (A): With the help of a Bomb calorimeter, the lower calorific value of a solid or liquid fuel can be determined, as the water vapour formed is carried away by the exhaust gases.
Reason (R): The lower calorific value of a fuel is the net value of heat available found by subtracting the latent head of the water formed and carried away by exhaust gas from the higher calorific value.
Option (A)
Both A and R are true and R is the correct explanation of A
Option (B)
Both A and R are true but R is NOT the correct explanation of A
Option(C)
A is true but R is false
Option(D)
A is false but R is true
Correct Option:
(D)
Question Solution:
Bomb calorimeter is a closed constant volume process in which after combustion the product is allowed to cool which raises the temperature of jacket water.
