Answer to Question #343462 in Mechanics | Relativity for nella

Question

What happens to the mass of water in a

pot when it cools, assuming no

molecules escape or are added? Is this

observable in practice? Explain.

Answer 1

Assume no molecule escape or are added to the mass of water in pot, if the mass of water is cooled then its mass will increase due to conversion of thermal energy into mass relativistically.
