Afluid in equilibrium within a vessel exerts pressure intensity to all parts of the fluid, according to principle

A fluid in stability in a vessel applies pressure energy to the complete fluid, according to Pascal's principle.

Explanation:

Pascal's principal explains that Pressure changes applied to the outer part of an confined fluid are transferred uniformly throughout the fluid.

Pascal's law  is a one of the laws in fluid mechanics.

This is given by Pascal. This law  explains  that a pressure change at any point in a limited close fluid is transferred throughout the fluid such that the same change occurs everywhere.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

this would be about 43%
