How does adding heat affect liquid water?
Gas, because all the molecules have enough energy to have escaped at 110 degrees
Its molecules move faster
Liquid to gas
It undergoes a physical change from a solid to a liquid
Heat energy
The coloring will move through the hot water faster because hot water has more energy
Burning a candle
