Ana is creating models to show atoms of solid bromine, liquid bromine, and gaseous bromine. How should her three models differ?

• The size of the atoms should vary depending on the state

• The mass of the atoms should vary depending on the state

• The motion of the atoms should vary depending on the state

• The identity of the atoms should vary depending on the state

Which properties describe all matter?

• being able to be seen in nature

• having energy and temperature

• being able to be easily measured

• having mass and taking up space

Identifying the independent and dependent variables in an experiment will help you better interpret and convey results. What is the difference between independent and dependent variables in an experiment?

• The independent variable is always a number, and the dependent variable is never a number.

• The independent variable is what you control, and the dependent variable is what changes as a result.

• The dependent variable is what the investigator controls, and the independent variable is what happens as a result of this.

• The dependent variable is typically found in the first column of a table, and the independent variable is typically found in the second column.

In 1897, Joseph Thomson discovered that atoms contained electrons. He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery. Since Thomson's discovery, atomic theory has been further modified. What is the best explanation for why scientific theories are modified?

• Theories more than ten years old are usually out of date.

• Scientists want to prove that the work of other scientists is wrong.

• New evidence that supports a revision prompts scientists to modify the earlier theories.

• So much information is available today that it is harder to focus research and disprove theories.

Renee rolls a steel ball down a ramp. She conducts multiple trials by releasing the ball from varying heights on the ramp. For each trial, she measures and records the release height of the ball and the distance the ball travels from the ramp before falling to the ground. In this experiment, which variable is the independent variable?

• distance traveled by the ball

• path of ball once it leaves the ramp

• height from which the ball is released

• time it takes the ball to hit the ground

• density

What is the volume of a rectangular solid that is 40 centimeters long, 10 centimeters wide, and 5 centimeters high?

• 400 cm3

• 500 cm3

The picture shows that a key is placed into a graduated cylinder filled with water. What process should be used to determine the volume of the key?

• Measure the water level before and after placing the key and calculate the difference.

• Weigh the key and use its density to find the volume.

• Use a ruler to measure the dimensions of the key.

• Estimate the volume based on the size of the key.
