You decide to boil water to cook noodles. you place the pan of water on the stove and turn on the burner. a. how does the behavior of the water molecules change as the pan of water is heated? b. what about your answer to (a) would change if there were more water in the pan?

A. As the pan of the water is heated, the water molecules moves faster and father apart.
As the water is heated, the water molecules gains more kinetic energy as the result of the heat that is been added by the stove. The gained kinetic energy allows the molecules to move faster and to move father away from one another.
b. If there are more water inside the pan, the same phenomenon experienced in the [a] above will still occur, but this time around it will take a longer period for the reaction to occur. This is because, there are more water particles in the pan and therefore it will take longer time before the heat from the stove circulate round all the particles.

When you are making a guess you are forming a hypothesis
