The third law of thermodynamics relates the entropy (randomness) of matter to its absolute temperature. Which of the following statements are in agreement with the third law of thermodynamics? Check all that apply. Check all that apply. At absolute zero, the interatomic distance within a crystal is minimized. As the temperature of a perfect crystal increases, the random vibrations of the molecules decrease. At zero degrees kelvin, substances maximize entropy. In a gaseous state, the entropy of the system is...

QUESTION 15 Which statement A-D about the first law of thermodynamics (AEsystem-q+w) is not correct? O q is the energy added to or removed from the system by a temperature difference. O w is the energy added to or removed from the system by a deformation: that is, a force moves something. AEo stem is the change in the Gibbs free energy of the system. O If the only work that is done is P-V work, then q -the change...
