Homework Help: physics

A Carnot engine, operating between hot and cold reservoirs whose temperatures are 800.0 and 400.0 K, respectively, performs a certain amount of work W1. The temperature of the cold reservoir is then lowered to 200.0 K (see the drawing), and the work done by the engine is W2. Assuming that the input heat QH is the same in both cases, what is the ratio W2/W1?
