We are being asked to identify whether the following statements is true or false


Recall the Three Laws of Thermodynamics are:

  • First Law: energy is neither created nor destroyed; it can only be converted from one form to another
  • Second Law: in any spontaneous process, the entropy of the universe (system + surroundings) increases
  • Third Law: At 0 K, the entropy of a perfect crystalline solid is zero
