A small amount of sodium chloride (NaCl) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.)
Use these sketches to answer the questions in the table below.
Would heat be absorbed or released if the system moved from Stage C to D?
a) absorbed b) released c) neither absorbed nor released
