### Experiment Steps

Michael conducted an experiment to test if matter is conserved after a phase change. He filled an empty bottle with 50 mL of water and placed it in a sunny window until the liquid water changed to water vapor. The steps of the activity are listed in the table below but might not be in the correct order.

 Experiment Steps 1 Find the mass of the bottle, lid, and water vapor. 2 Pour 50 mL of water into an empty bottle. 3 Find the mass of the bottle, lid, and 50 mL of water. 4 Place a lid on the opening of the bottle to tightly seal it.

18. Which shows the experiment steps in the correct order?

19. According to the text, which would be the control of the experiment?

A. the water

B. the water vapor

C. the location of the bottle on the sunny window

D. the time Michael waits for the water to become water vapor

20. Why does Michael want to find the mass of the water and water vapor and not the weight?

A. The mass is the amount of matter in the water and water vapor.

B. The mass measures the gravitational force on the water and water vapor.

C. The mass varies by location.

D. The mass is measured in newtons.
