Heat and Thermal ExpansionHard
Question
If mass - energy equivalence is taken into account, when water is cooled to from ice the mass of master should :-
(Note : The mass energy of an object is the energy equivalent of its mass, as given by E = mc2 where m = mass of object & c = speed of light)
(Note : The mass energy of an object is the energy equivalent of its mass, as given by E = mc2 where m = mass of object & c = speed of light)
Options
A.increase
B.remain uncharged
C.decrease
D.First increase then decrease
Solution
When water is cooled to form ice, the energy is released as heat so mass of water decreases.
