Questions: For the following 3 experimental set-ups, identify the independent variable, dependent variable, a few controlled variables, and then write a valid hypothesis for the experiment.

-Justin is growing a garden and has many different types of liquids with which he could water his plants. He has water, coffee, milk, and fertilizer dissolved in water. He wants to know which liquid will help his tomato plants grow the best.
Independent variable:
Dependent variable:
Controlled variables:
Hypothesis:

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
