The volume occupied by a sample of gas which is placed 8cm above the floor is 480 mL when the pressure is 36˚C. What must be the temperature (in Celsius) of the gas to make its volume become 650 mL? (use GRESA method)

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.

answer(20) psi;
