Example Input: Question: John was playing with alkanes in his lab. If he increased the amount of carbon atoms in an alkane, what would happen to the boiling point of that alkane? 
 Answer: increase
Example Output: Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.

Example Input: Question: If Milo starts rubbing two surfaces together quickly and then decrease the speed, what happens to the amount of energy produced? 
 Answer: decreases
Example Output: Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer.

Example Input: Question: Compared to a small rock, large granules of sand are able to dissolve 
 Answer: harder
Example Output:
Smaller pieces dissolve more easily.
