Task: Question Generation
Input (English): Background Paragraph: Changes of state from solid to liquid and from liquid to gas occur when matter gains energy. The energy allows individual molecules to separate and move apart from one another. It takes more energy to bring about these changes of state for polar molecules. Although hydrogen bonds are weak, they add to the energy needed for molecules to move apart from one another, so it takes higher temperatures for these changes of state to occur in polar compounds. This explains why polar compounds have relatively high melting and boiling points. The Table below compares melting and boiling points for some polar and nonpolar covalent compounds. 
Story: Andrew is thirsty and wants some cold water. He puts a bottle in the freezer but leaves it in too long so it freezes. Being impatient he then takes the bottle and runs it under soe hot water for a few minutes.
Output (English): Will the energy of the water molecules in the bottle increase or decrease when Andrew runs hot water on the bottle?
