Question

In a reaction, the conservation law of energy states that the initial energy and the final energy are equal, provided that:

विकल्प

• No new particles are produced in the reaction

• The energy associated with mass is also included

• The reaction is carried out at constant volume

• The total mass remains exactly constant throughout

Answer 1

The conservation law of energy states that the initial energy and the final energy of a reaction are equal, provided the energy associated with mass is also included. This inclusion of mass-energy is essential for the law to hold in nuclear processes.
