EOY Review

A student has a pure gold coin and a pure gold necklace. Which statement best explains why the gold objects look similar?

• All atoms of the same element come from the same mineral deposit.

• All atoms of the same element are found in a liquid state of matter.

• All atoms of the same element have the same properties.

• All atoms of the same element have different properties.

This table shows the boiling point and melting point of four elements. A scientist has a liquid sample of one of these four elements. The scientist knows that the temperature of the sample is less than 1000°C. What is the identity of the sample?

• copper

• gold

• iron

• silver

Refer to the data table and diagram showing the experiment with plastic and marble tiles and ice cubes. Which part of the experiment provides evidence of a change in particle motion?

• Both of the ice cubes had the same initial temperatures.

• Both of the ice cubes changed state from a solid to a liquid.

• The plastic tile had a higher initial temperature than the ice cube on the tile.

• The plastic tile took more time to transform the ice cube than the marble tile.

A teacher placed a pot containing liquid water onto a hot stove. This table shows water temperature measurements recorded by the teacher: Time (minutes): 1, 2, 3, 4, 5 Temperature (°C): 32, 65, 100, 100, 100 Why did the water temperature remain constant after 3 minutes?

• The water boiled at 3 minutes, so any heat added to the water after this time would be used to transition the liquid into a gas.

• The water melted at 3 minutes, so any heat added to the water after this time would be used to transition the liquid into a solid.

• Heat could not be transferred to the water after 3 minutes, which means that the pot must have absorbed all the heat from the stove.

• Heat could not be transferred to the water after 3 minutes, which means that the atmosphere must have absorbed all the heat from the stove.

The image shows two objects placed in different bowls containing the same type of liquid. If each object displaces the same volume of liquid, which has a mass of 300 grams (g), then which of the following could be true?

• Object 1 has a mass of 150 g, and Object 2 has a mass of 450 g.

• Object 1 has a mass of 450 g, and Object 2 has a mass of 150 g.

• Object 1 has a mass of 250 g, and Object 2 has a mass of 250 g.

• Object 1 has a mass of 450 g, and Object 2 has a mass of 450 g.

What should Evan most likely do to make the water temperature decrease to below 0°C?

• Evan should add twice as much ice so more heat energy is transferred from the water to the ice.

• Evan should add twice as much ice so more cold energy can be transferred from the ice to the water.

• Evan should put the bin in an area that is lower than 0°C, so all of the heat energy from the water can be transferred to the surrounding air.

• Evan should put the bin in an area that is lower than 0°C, so all of the cold energy from the surrounding air can be transferred to the water.

The image shows a beaker filled with water on a metal beaker stand above a Bunsen burner flame. Water at the bottom of the beaker becomes hot, causing it to rise. The colder surrounding water is more dense, and so it moves to the bottom of the beaker. The colder water is then heated at the bottom, creating a cycle of moving water. What form of heat transfer is occurring in the water?

• conduction

• convection

• expansion

• radiation

A student conducts an experiment using a metal ball and ring attached to a stand. The metal ball moves through the ring at room temperature. The student then heats the ball on a burner and tries to pass it through the ring again, as shown in the image of the experiment setup. Which BEST explains why the metal ball cannot pass through the ring after being heated?

• The ball expands and becomes larger in size.

• The ring expands and becomes larger in size.

• The ball contracts and becomes smaller in size.

• The ring contracts and becomes smaller in size礁
