The production of light during a change can indicate what?

Answer and explanation

Correct answer: रासायनिक अभिक्रिया होने का

The production of light indicates an energy change and can be a sign that a chemical reaction is occurring. For example, when magnesium burns, it produces a bright white light and forms a new substance, magnesium oxide. In contrast, a change of shape, filtration, and freezing are generally physical changes in which no new substance is formed.
