10. Entropy can be calculated by a relationship proposed by Ludwig Boltzmann:52S = InWwhere k = 1.38 x 10 23 J/K (Boltzmann constant) and W is the number of ways a certain state can beobtained. (This equation is so important that it is engraved on Boltzmanns tombstone, see below.)

Suppose your room could be arranged in 1000 different ways. What is the corresponding entropy? Data: Boltzmann constant k=1.38×10-23 J/K.

The entropy change for the processH2O(s)⟶H2O(l)is 27.9 J/K and requires that the surroundings transfer 35.0 kJ of heat to the system. Calculate the change in entropy for the universe in kJ/K at 56.2 °C.

The heat of vaporization AH, of ethanol (CH,CH,OH) is 38.6 kJ/mol. Calculate the change in entropy AS when 7.2 g of ethanol condenses at 78.4 °C. Be sure your answer contains a unit symbol and the correct number of significant digits.

Q17.24 A 3.5 mol sample of an ideal gas is compressed from 20.8 L to 12.5 L. What is its change in entropy (in J/K)? Give only the numerical part of your answer.
