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.

A fresh apple is placed in a tightly sealed glass jar. The total mass of the jar and apple is measured. After a week, the apple in the jar begins to rot. The total mass is measured again. Which can be accurately predicted?

• Total mass will not change because the amount of matter in the jar and the apple will not change.

• The mass of the jar will be the total mass because no matter will be left in the jar after the apple rots.

• The total mass will increase because the rotting apple will produce gases.

• The total mass will decrease because the rotting apple will release heat.

Thomas has 1,200 g of salt water. Which are the correct measures of salt and water before they were mixed?

• 600 g of salt and 600 g of water

• 900 g of salt and 200 g of water

Tim made a metal object with a weight of 75g. Using the table, what metals did he use to make the object?

• aluminum and lead

• aluminum and tin

• iron and tin

• iron and lead

What is true about the weight of the tray between minutes 0 and 2?

• The tray weighs less because the ice melted.

• The tray weighs less because water was lost.

• The tray weighs the same because no water was lost when the ice melted.

• The tray weighs the same because lost ice weight was replaced by water weight.

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?

• mass of Beaker 1 < mass of Beaker 2 < mass of Beaker 3

• mass of Beaker 3 < mass of Beaker 1 < mass of Beaker 2

• mass of Beaker 3 < mass of Beaker 2 < mass of Beaker 1

• mass of Beaker 2 < mass of Beaker 1 < mass of Beaker 3

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?

• The mass of both the soda bottle and balloon setup increases as the balloon expands.

• The mass of both the soda bottle and balloon setup remains the same as the balloon expands.

• The mass of the soda bottle remains the same, but the mass of the balloon increases as it expands.

• The mass of the bottle increases, but the mass of the balloon remains the same as it expands.

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.
