Homework Statement


A sample containing 3.65 mol of a monatomic ideal gas is heated from 289K to 458K, and the entropy remains constant. If the initial volume of the sample was 0.0980m^2, by what factor did the pressure increase or decrease during this process?

Homework Equations




The Attempt at a Solution


it's isentropic. use the formula to get volume and then substitute it into ideal gas formula? would love some hints please!
