Without doing further calculations, which of the following statements apply to the entropy change of the surroundings for the problem above?
ΔSsurroundings will not change.
ΔSsurroundings will be positive.
|ΔSsurroundings| = |ΔSsteam|
|ΔSsurroundings| < |ΔSsteam|
ΔSsurroundings will be negative.

If there are 3 particles with a total energy of 12 J, which system would have more entropy and why? Question 21 options: System A has more entropy because it has greater separation between energy levels and hence more microstates than system B. System B has more entropy because it has more than two microstates, whereas System A only has two microstates possible. System A has more entropy because it has three microstates, whereas System B has less than three microstates possible. System B has more entropy because it has more than three microstates, whereas System A only has three microstates possible. System A has more entropy because it has more than one microstate, whereas System B only has one microstate possible.arrow_forwardTwo different gases occupy the two bulbs shown here.
