Answer
An (aq) solution of NaCl, in which the sodium chloride compound is existing as dissolved ions, is more disordered than the solid form.
Carbon dioxide gas has higher entropy, more disorder, because the gaseous state is in constant motion as compared to the solid state.
Hot water has higher entropy because heat applied to particles causes them to be in motion, thus increasing the disorder of the system.
