Question

When heat passes from a hot to a cold body there is a change in mass. Do you agree?

Answer 1

Answer:

hey mate

Explanation:

Yes, in a reference frame where the total momentum of the composite object is zero, then E = m c 2 , and that includes thermal energy. Thermal energy is very, very, very small, so no, it is not measurable as mass. Yes mass does change but it is counted as negligible.

hope its help mark as brailist ;)
