I HAVE TRIED HALF AS MUCH, and THATS NOT THE RIGHT ANSWER.
Homework Answers
here,
specific heat is a intrinsic quantity
so, the vaue of specific heat is independent of mass of substance present
and
dependent on the nature of the substance
as we have only water for both the cases
so, the value of specifc heat for 2 Kg water and 1 kg water is same
