    Need help with a question involving heat engines, the carnot cycle and entropy.

    thats great, thanks anybody have any idea for e), even just a prod in the right direction would be excellent.

    Need help with a question involving heat engines, the carnot cycle and entropy.

    The Attempt at a Solution For a) I imagine it is easier to control the temperature of the hot reservoir because you could use a constant heat source e.g. bunsen burner. c) melting/freezing water. d) Entropy of the environment increases and the entropy of the universe always increases...
