Question 4
/1
Liquid water is boiling in a pan on a stove. The burner on the stove is set on “LOW.” While the water is
boiling the burner is turned to the “HIGH” seħng. What happens to the temperature of the liquid water while it is boiling?
It remains the same.
It increases, and it does so at the same rate as when the burner was on “LOW.”
It decreases slightly due to the extra boiling.
It increases, and it does so at a faster rate than when the burner was on “LOW.”
It decreases very much due to the extra boiling.
Question 5
/1
Liquid water is boiling in a pan on a stove. The bubbles that move through the liquid are:
heat energy because this is one way that we can prove that heat is really matter.
air trapped in the water.
liquid water molecules turning into carbon dioxide.
liquid water molecules turning into a gas (steam).
Question 6
/1
Once a liquid evaporates and turns into a gas, the gas molecules are free to increase their
temperature as high they want True
False
