Question

Students were asked to place a mint in their mouths and determine how long it took for the mint to dissolve. The

condition of the mint varied in each student group. One group of students were asked to leave a whole mint in their
mouth, not moving it around, and let it dissolve. Another group swirled a whole mint around in their mouths, while the
other groups used mints broken into smaller pieces. See the chart for all of the manipulated variable.
After reviewing that data table, what kind of result would you predict for the swirled, whole mint?
A) The time is likely between 10-30 seconds.
B) The time is likely between 40-80 seconds.
C) The time is likely between 90-160 seconds
D) The time is likely between 100-200 seconds.

Answer 1

B. The time is likely between 40 - 80 seconds.

Step-by-step explanation:

One group of students were asked to leave a whole mint in their mouth, not moving it around, and let it dissolve, which takes very long time to dissolve since there is lower frequency of collision among the saliva particles and mint.

Another group swirled a whole mint around in their mouths, so the frequency of collision between the saliva and the mint particles increases, there by increase in dissolving capacity, but the timing will be lesser when compared to other groups used mints broken into smaller pieces.

So the time for swirling is likely between 40 - 80 seconds.
