A student notices that an inflated balloon gets larger when it is warmed by a lamp. Which best describes the mass of the balloon as a result of this change?

• The mass of the balloon increases because the size of the balloon has increased.

• The mass of the balloon increases because the temperature of the balloon has increased.

• The mass of the balloon stays the same because the gas inside the balloon still has the same mass after it warms up.

• The mass of the balloon stays the same because warming decreases the mass enough to cancel out the effect of increasing the size.

Which is an example of a different substance being formed?

• Glass breaking

• Metal melting

• Water freezing

• Wood burning

An hour after cutting an apple into slices, a chef observes that the apple slices have a brown color. How are the changes to the apple best classified?

• The cutting of the apple and change in its color are physical changes.

• The cutting of the apple and change in its color are chemical changes.

• The cutting of the apple is a chemical change, and the change in its color is a physical change.

• The cutting of the apple is a physical change, and the change in its color is a chemical change.

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?

• The mass of the can filled with ice would have a greater mass than the can with water after the ice had melted.

• The mass of the can filled with ice would have a smaller mass than the can with water after the ice had melted.

• The mass of the can filled with ice would have the same mass as the can with water after the ice had melted.

• It is impossible to determine which can had more mass without more information about the ice and the can.
