When the mass of something decreases, does it emit or absorb energy?
If mass of something decreases, does it emit or absorb energy.
Explanation of Solution
Introduction:
The amount of energy E is directly related to mass m as per the Einstein's Mass energy equation. Energy and mass are same.
A change in energy of an object at rest takes place along with change in its mass.
As mass of an object decreases it emits the energy equal to loss of mass. For all chemical reactions that emit energy, there is decrease in mass.
Conclusion:
If the mass of something decreases, energy is emitted.
