Thermodynamics Quizzes Online & Trivia

The second law of thermodynamics asserts that for a thermodynamically defined process actually to transpire, the amount of the entropies of the participating bodies must increase. In an idealized limiting case, that of a reversible process, this sum remains unchanged. It asserts that the total entropy of an isolated system can never decrease over time. The total entropy can remain constant in typical cases where the system is in a steady state (equilibrium) or is undergoing a reversible process. The second law of thermodynamics concerns the quality of energy. As energy is transferred, more and more is wasted.

3 expansion it does not involve heat transfer

Meltingice isendothermic-- you can see this by putting a thermometer in a glass of warm water, adding an ice cube, and watching the temperature go down as the icemelts.

Increases to more than twice its original value.

The amount of energy required to increase the temperature of a substance

They're commonly confused as the same but there are many differences between the two processes. Adiabatic expansion is an increase in volume while pressure is maintained constant. When this occurs, temperature also increases.  Isothermal expansion, on the other hand, is an increase in volume while temperature is maintained constant. When this occurs, pressure decreases.
