In the water vapor state, water molecules are flying around like crazy fan girls at a One Direction concert. What happens to the molecules when they transform into a liquid state? Then when they transform into solid state?
The molecules cool and come together at maximum density. When cooled even more, the molecules become organized and spread out slightly, decreases density which is why ice floats.

In its first month of operation, America's first power station produced enough power to light a certain number of light bulbs. Within 14 months, the plant was producing 15 time that much power. The sum of the bulbs lit in the first month and in the 14 month is 6,400 bulbs. How many bulbs could be lit with the power produced in this first month?
x + 15x = 6400
6400 / 16 = 400 bulbs in the first month
