Pascal's law is a principle in fluid mechanics that states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

This principle is stated mathematically as: P= P + rgh

Nuclear power energy source generates radioactive waste.

No. Boiling water is not a chemical change. Because in this process it doesn't loss its properties. It just changes its state i.e, from liquid state to gaseous.

Hence, Boiling water is a Physiacl change and not a chemical change.
