Question

Which of the following statements is false? a. Temperatures of a few nanokelvins can be achieved in a Bose-Einstein condensate. b. A perfect crystal of any substance at 0 K has minimum entropy. c. The standard molar entropy of a substance at temperature T is a measure of the quantity of energy that must be dispersed in that substance for it to exist at T. d. A reversible process is one in which a large change in conditions can reverse its direction. e. Entropy is a measurement of the nanoscale dispersal of energy in a sample of matter.

Answer 1

Answer:

Option D

A reversible process is one in which a large change in conditions can reverse its direction.

Explanation:

A. Temperatures of a few nanokelvins can be achieved in a Bose-Einstein condensate. TRUE

b. A perfect crystal of any substance at 0 K has minimum entropy. is TRUE

c. The standard molar entropy of a substance at temperature T is a measure of the quantity of energy that must be dispersed in that substance for it to exist at T. is TRUE

d. A reversible process is one in which a large change in conditions can reverse its direction. is FALSE

e. Entropy is a measurement of the nanoscale dispersal of energy in a sample of matter. is TRUE

A reversible reaction is one that can return to it's normal direct even if an infinitesimal change is applied to some of it's conditions.
