Question #2
What is true about the weight of the tray between minutes 0 and 2?
A)
B)
C)
D)
The tray weighs less because the ice melted.

Question #3
Emily determined the mass of a sealed can filled with crushed ice. The ice slowly melted in
the can, and no water vapor escaped as it melted.
After the ice melted, what is the best prediction about the mass of the can with water?
A) The mass of the can filled with ice would have a greater mass than the can with water after the
ice had melted.
B) The mass of the can filled with ice would have a smaller mass than the can with water after
the ice had melted.
C) The mass of the can filled with ice would have the same mass as the can with water after the
ice had melted.
D) It is impossible to determine which can had more mass without more information about the ice
and the can.
Question #4
A student selects three identical beakers containing 50 mL of water each. She adds 20 g of salt in
Beaker 1, 15 g of sugar in Beaker 2, and 30 g of fine sand in Beaker 3. She mixes the contents in each
beaker well.
How do the masses of the three beakers compare?
A
mass of Beaker 3 < mass of Beaker 1 < mass of Beaker 2
B
mass of Beaker 1 < mass of Beaker 2 < mass of Beaker 3
C
mass of Beaker 3 < mass of Beaker 2 < mass of Beaker 1
D
mass of Beaker 2 < mass of Beaker 1 < mass of Beaker 3

Question #5
Baking soda and vinegar are placed in a soda bottle with a balloon stretched over the top. Suddenly,
the balloon expands and fills with a gas. The image shows the soda bottle in the beginning and
during the experiment.
Which statement best describes the mass of the soda bottle and balloon setup in this experiment? A
The mass of both the soda bottle and balloon setup increases as the balloon expands.
B
The mass of both the soda bottle and balloon setup remains the same as the balloon
expands.
C
The mass of the soda bottle remains the same, but the mass of the balloon increases as it
expands.
D
The mass of the soda bottle increases, but the mass of the balloon remains the same as it
expands. https://app.masteryconnect.com/materials/1060983/print

Question #6
A student inflates two similar balloons to the same volume. One balloon is inflated by blowing air into
it, while the other balloon is inflated using helium. The student notices that the balloon inflated with
helium floats, while the balloon inflated with air sinks.
Which statement best explains the difference in the balloons?
A
The mass of the air inside the balloon is lighter than the mass of the helium, which causes the
balloon to sink.
B
The mass of the helium inside the balloon is lighter than the mass of the air, which causes the
balloon to float.
C
The mass of the balloon inflated with helium is heavier than the surrounding air, which causes
the balloon to float.
D
The mass of the balloon inflated with air is lighter than the surrounding air, which causes the
balloon to sink.
Question #7
A student added 20 g of baking soda to a plastic bag containing 20 mL of vinegar and immediately
sealed the bag. The student observed the vinegar and baking soda reacted to release a gas, which
caused the bag to expand.
What happened to the total mass of the substances in the sealed bag after the reaction?
A
The total mass stayed the same. B
The total mass decreased.
C
The total mass increased.
D
The bag absorbed some of the mass.

The diagram shows a glass of clear liquid (A). A yellow dye capsule (B) is added to it.
What will happen in the glass C ?
A) Capsule dissolves but liquid remains clear.
B) Capsule dissolves and liquid changes to a yellow color.
C) Capsule does not dissolve.
D) Capsule does not dissolve, but the liquid changes to a yellow color.
Question #9
Folded paper and frozen water are examples of a substance being altered with no new
substance being formed.
Which term best defines this process?

that surround those large bodies of water?
A) The areas near large bodies of water usually have a cold, dry winter.
