Students were asked to place a mint in their mouths and determine how long it took for the mint to dissolve. students were asked to leave a whole mint in their mouth and let it dissolve. other student groups varied how the mint was treated. one group was asked to swirl the whole mint around in their mouth; another group cut the mint in half, and last group broke the mint into small pieces. the results are displayed in the table. what conclusion can be drawn from the results? a) surface area did not play a role in this activity. b) agitation of the mint increased the dissolving time. c) as surface area increased, the dissolving time decreased. d) the heat of the mouth to decrease the time for the mint to dissolve. solute time to dissolve (seconds) whole mint 192 mint cut in half 108 swirled mint 76 mint cut into small pieces 38
