Q4:
Some water vapor in a container is cooled. It first condenses to become water and then freezes to become ice. The temperature of the contents of the container are recorded every minute, and the results are shown in the graph.
What state was the water in between 0 and 5 minutes?
- ASolid
- BLiquid
- CGas
What state was the water vapor in between 40 and 45 minutes?
- ASolid
- BGas
- CLiquid
What word describes what is happening between 5 and 15 minutes?
- AFreezing
- BEvaporation
- CCondensation
- DSublimation
- EMelting
What word describes what is happening between 35 and 40 minutes?
- AFreezing
- BSublimation
- CCondensation
- DEvaporation
- EMelting
Q5:
The diagram shows water in its three different states: ice, liquid water, and steam.
What word is used to describe liquid water changing to ice?
- ACondensing
- BMelting
- CBoiling
- DFreezing
- ESublimating
What word is used to describe liquid water changing to steam?
- AEvaporating
- BCondensing
- CMelting
- DFreezing
- ESublimating
Under certain conditions, ice can skip the liquid phase entirely and become steam. What word is used to describe this?
- ACondensing
- BMelting
- CSublimating

Q6:
What word describes a substance changing from a gas to a liquid?
- AFreezing
- BMelting
- CEvaporating
- DCondensing
- EBoiling
Q7:
Some ice is placed in a beaker and heated using a Bunsen burner. It eventually melts and becomes water. The water is then heated until it is boiling. The temperature of the contents of the beaker is recorded every minute, and the results are shown in the graph.
What state was the water in between 0 and 5 minutes?
- ALiquid
- BGas
- CSolid
What state was the water in between 10 and 30 minutes?
- ALiquid
- BSolid
- CGas
Between 30 and 40 minutes, the water was undergoing a change of state. Which word is used to describe this change of state?
- AEvaporation/boiling
- BCondensation
- CSublimation
- DMelting
Q8:
Which of the following correctly describes what is meant by “freezing?”
- A“Freezing” is the process of cooling a substance below .
- B“Freezing” is the process of a substance changing from a gas to a liquid.
- C“Freezing” is the process of cooling a substance to absolute 0.
- D“Freezing” is the process of a substance changing from a liquid to a solid.
- E“Freezing” is the process of a substance changing from a solid to a liquid.
Q9:
Heating a substance increases the of the substance, which leads to a or a .
- Ainternal energy, change in mass of the substance, change in state
- Bdensity, change in temperature, change in state
- Cinternal energy, change in temperature, change in mass of the substance
- Dinternal energy, change in temperature, change in state
- Edensity, change in the mass of the substance, change in state
