10. Which of the following statements describes the state of matter known as gas?
A. Gas is the state of matter that has a definite shape and volume.
B. Gas is the state of matter that has no definite shape or volume.
C. Gas is the state of matter that has less mass than the liquid from which it forms.
D. Gas is the state of matter that has more mass than the liquid from which it forms.
11. A child is upset because his ice cream is melting. He thinks he now has less ice cream. Which
choice explains what is wrong with his reasoning?
A. He actually has more, not less, ice cream.
B. The mass will increase if he freezes the melted ice cream.
C. Mass is lost only during certain changes of state, such as freezing.
D. No mass is lost during a change of state, such as melting.
12. Ying is testing the properties of the states of matter. She plans to test how the volume of a
liquid changes by first filling a 50-mL graduated cylinder with water and then pouring the
water into a 100-mL beaker. What volume will she observe in the beaker?
A. It will be about 100 mL because it will fill the beaker.
B. It will be about 50 mL because liquids have a constant volume.
C. It will be about 50 mL because the liquid will retain the shape of the graduated cylinder.
D. It will be about 25 mL because the beaker is much wider than the graduated cylinder is.
13.
Dry ice is solid carbon dioxide. At room temperature, it changes directly into a gas.
Which of the following best describes this change?
A. Deposition causes the particles of the carbon dioxide gas to lock into place.
B. Freezing occurs due to a decrease in the kinetic energy of the particles.
C. Sublimation occurs due to an increase in the kinetic energy of the particles.
D. Evaporation results in a reduction of the mass of carbon dioxide.
14. Cassandra is creating a model to show atoms of solid bromine, liquid bromine, and gaseous
bromine. How should her three models differ?
A. The size of the atoms should vary depending on the state.
B. The motion of the atoms should vary depending on the state.
C. The identity of the atoms should vary depending on the state.
D. The mass of the atoms should vary depending on the state.
