Question

If a substance is heated or cooled,the the mass of that substance increase or decrease

Answer 1

Mass will remain constant

Explanation:

when a substance solid liquid and gas heated all get expanded due to addition of heat. while on cooling, heat leaves from them resulting in slowing down of molecular vibrations. matter contract while atoms getting closer to one another. But there will be no change in mass.

Answer 2

If a substance is heated or cooled,the the mass of that substance neither increases nor decreases. It remains constant.

- Mass of a substance does not depend on the temperature of the substance. - It is independent of the temperature of substance.

- So, whether we heat or cool the substance, it will have no effect on the mass of the substance. The mass will remain the same.
