Solid, liquid, gas, plasma
Gas, plasma, liquid, solid
Liquid, solid, plasma, gas
Plasma, gas, liquid, solid
- 5. Multiple Choice
Which statement correctly describes a difference between solids and gasses?
Solids are made up of particles; gasses are not.
Solids take the shape of their containers; gases have definite shape
Solids have a definite volume; gases have an indefinite volume
Solids have indefinite shape; gases have an indefinite shape
- 6. Multiple Choice
How would a balloon left in a car on a hot day change?
The gas particles will move quickly due to hot temperatures and the volume will expand.
The gas particles will slow down to the hot temperatures in the car.
The heat in the car will allow the balloon to shrivel.
None of the above.
- 7. Multiple Choice
A student moved a sample of matter from a small container to a larger container. The matter changed shape and did not fill the container completely. What was the phase of the matter?
solid
liquid
gas
plasma
- 8. Multiple Choice
Which term best describes the process by which particles of a matter of a non-boiling liquid enter the gas state?
sublimation
evaporation
melting
freezing
- 9. Multiple Choice
When a substance changes from a liquid to a solid, which of the following is TRUE?
The molecules of the substance get heavier because solids gain weight during a phase change.
The molecules of the substance change the odor of the substance.
The molecules of the substance connect more strongly to one another because solids have a stronger attraction in particles.
The molecules of the substance change from hard to soft due to solids having a weak attraction in particles .
- 10. Multiple Choice
Dry ice is an example what falls during the winter times in Mars? What phase change is occurring?
freezing
condensation
sublimation
boiling
- 11. Multiple Choice
Which scenario is NOT an example of Boyles’ Law?
When the top of a spray can is pressed. The volume inside the can gets reduced and the paint is thrown out due to great pressure.
Tissues near the air filled spaces of your body, such as lungs can become affected. The lungs of a scuba diver can get damaged due to the immense pressure of water. As the diver descends in water, the volume of air in the body decreases.
In winter times, the temperature of the air inside the body decreases, so the temperature shrinks the lungs and running may become difficult during the cold seasons
A balloon is squeezed, making the volume smaller.
- 12. Multiple Choice
Which characteristic is NOT of a gas?
can not be compressed
indefinite volume
indefinite shape
weak attraction between the particles
- 13. Multiple Choice

the temperature would increase
the temperature would decrease
the pressure would decrease
the pressure would increase
- 14. Multiple Choice

True
False
- 15. Multiple Choice
True or False: The particles going through the boiling phase have slowed down due to a decrease in temperature.
True
False
- 16. Multiple Choice
The molecules of a substance are moving rapidly in a container. The molecules do not interact with each other. If the container is opened, the molecules will escape from the container. In what phase of matter are the molecules in the container?
solid
liquid
gas
plasma
