Josh works for a construction company that uses 150 pounds of gravel for each driveway they pour.
He can buy a dump truck load with 30,000 pounds of gravel or a pick-up truck load with 2,500 pounds.
Which amount should he buy so that no gravel is left after all of the driveways are poured and why?
A.
Josh should buy the pick-up truck load because 2,500 ÷ 150 = 16 23. There is enough gravel to
pour 16 driveways with 100 pounds of gravel left. You cannot divide 30,000 ÷ 150 evenly.
B.
Josh should buy the pick-up truck load because 2,500 ÷ 150 = 160 23. There is enough gravel to
pour 160 driveways with 100 pounds of gravel left. You cannot divide 30,000 ÷ 150 evenly.
C.
Josh should buy the dump truck load because 30,000 ÷ 150 = 200. There is enough gravel to
pour 200 driveways with none left. You cannot divide 2,500 ÷ 150 evenly.
D.
Josh should buy the dump truck load because 30,000 ÷ 150 = 2,000. There is enough gravel to
pour 2,000 driveways with none left. You cannot divide 2,500 ÷ 150 evenly.

What are the two things that happen to water molecules when heat energy is added to air?
Answer:
The more thermal energy added, the greater the attraction between molecules. The molecules gain kinetic energy, move farther apart, and become a gas. The water molecules become packed closer together, and their temperature increases. Each water molecule gives up kinetic energy and eventually stops moving.
