Amonatomic ideal gas undergoes an adiabatic expansion to double its volume. the same final state can be reached by an isobaric expansion followed by an isochoric cooling. what is the ratio of work done by the system between the first and the second processes?

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
