Maria puts 200 grams of ice cubes into a glass. She leaves the glass on the counter all day, and the ice melts into liquid water. The next morning, she comes back and finds the glass is empty!
Question:
If the glass is empty, where did all the matter go? Did the matter disappear?
The matter did not disappear—it changed state. The water evaporated into a gas and went into the air. Matter cannot be created or destroyed, only change forms.

Jamal left a sealed bottle of soda in the freezer overnight. The next day, the bottle had burst open and pieces of ice were sticking out. Why did this happen?
When the liquid froze, it expanded and took up more space. Since the bottle was sealed, the pressure caused the bottle to burst.

What tool measures temperature? What units?
Thermometer; Celsius or Fahrenheit

Ethan says water (H₂O) and oxygen gas (O₂) are the same thing because they both have oxygen atoms. Is he correct? Why or why not?
No, he’s not correct. Water is a compound made of hydrogen and oxygen atoms joined together, while oxygen gas is a molecule made of only oxygen atoms. They are different substances even though they both have oxygen.
