Sandra was trying to water the flowers with the hose, but even with the water turned up to full force she could not get it to reach the farthest flowers.

The thinner stream of water could travel farther because it was lighter.
B. Sandra added more energy to the water by making it swirl inside the hose.
C. The same amount of energy in the water was forced through a smaller space.
D. The warmth of Sandra's thumb increased the amount of energy in the water.
