Answer

Substance A is an element as atoms are not combined chemically.

Answer

Substance A is a compound as two different types of atoms are present.

Answer

Substance B is a mixture as the atoms can be separated by any physical process.

Question 17

A student designs an animation to visualize how the particles in a substance change when heat is added. How can the teacher verify that the animation is accurate?

Accepted Answer

Adding heat creates the effect of increased spacing between particles.

Answer

Adding heat creates the effect of increased particle size.

Answer

Adding heat creates the effect of decreased spacing between particles.

Answer

Adding heat creates the effect of decreased particle size.

Question 18

When heat energy is added to water in a pot on a stove, what changes occur to the water?

Accepted Answer

Particles move faster, and temperature increases.

Answer

Particles move slower, and temperature increases.

Answer

Particles move faster, and temperature decreases.

Answer

Particles move slower, and temperature decreases.

Question 19

During an experiment, a researcher applies pressure on a gas in a closed container using a movable piston, as shown.

Which model can be used to describe the particle arrangement of the gas before and after the pressure is applied if there is no phase change?

Accepted Answer

Question 20

The image shows two different atomic models made by two students.

What can be concluded about the models?

Accepted Answer

Model 2 is accurate because it shows protons and neutrons at the center of the atom and electrons in orbits around the center.

Answer

Both models are accurate because they show protons and electrons inside the nucleus.

Answer

Model 1 is accurate because the numbers of protons and electrons inside the atom are the same.

Answer

Both models are accurate because they contain positively charged protons and negatively charged electrons.

Question 21

Which model accurately shows the charges and relative sizes of each of the subatomic particles that compose an atom?
