A quantity of fluid occupies 0.56m³ at 1bar. After compression which follows PV^n =constant , the pressure and volume are 6.3bar and 0.14m³ respectively. Calculate the value
of the index 'n' and the work energy transfer. If the internal energy of the fluid increases by
85Kj during the process, calculate the heat energy transfer.​

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.
