The following diagram represents the Carnot cycle. Which of the following processes present when heat (q) is either absorbed by or released to the surrounding?

Is entropy increased or decreased in boiling water?

As a substance is subjected to pressure and/or temperature changes, it may undergo condensation, deposition, freezing, melting, sublimation, or vaporization. (a) Consider the phase diagram shown below and state the cha nges that take place upon going from points A to B to C to D. (b) Is the transition from C to D exothermic or endothermic?
