The top layer of your goose down sleeping bag has a thickness of 5.5 cm and a surface area of 1.0 m2 . when the outside temperature is -18 ∘c you lose 24 cal/hr by heat conduction through the bag (which remains at a cozy 35 ∘c inside). assume that you're sleeping on an insulated pad that eliminates heat conduction to the ground beneath you. (note: 1 cal = 4184 j)

do you have a formula possibly

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.
