If the gas in a thermally insulated container does work on the piston, what happens to the temeprature?

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

i think the answer is a and b

i wish you luck
