5. Consider a sample of 1 mol Kr (g) at a given temperature contained in a given volume. Which of the following statements are false? (A) The entropy of 1 mol Kr (g) is less than that of 1 mol Kr (s) at the same temperature. (B) The entropy of the sample is less than that of a 1 mol sample C4H10 (g) at the same temperature, contained in the same volume. (C) The entropy of the sample increases when the temperature is doubled. (D) The entropy of the sample decreases when the volume of the container is reduced (assuming the same initial and final temperatures). (E) Rotational and vibrational motions do not contribute to the overall entropy of the sample.
