When you freeze water it becomes a solid called
- A.
Rock
- B.
Ice
- C.
Water vapor
Correct Answer
B. IceExplanation
When water is frozen, it undergoes a phase change and transforms into a solid called ice. Freezing occurs when the temperature of water drops below its freezing point, causing the water molecules to slow down and arrange themselves in a regular pattern. This results in the formation of a solid structure with a fixed shape and volume. Ice is commonly found in nature, such as in glaciers, icebergs, and snow, and is also used for various purposes, including cooling and preservation.Rate this question:

When you melt something like ice it changes from a solid to
- A.
Gas
- B.
Liquid
- C.
Jonny Flynn
Correct Answer
B. LiquidExplanation
When ice is melted, it changes from a solid state to a liquid state. This is because the heat energy applied to the ice causes the water molecules to gain enough energy to break their rigid arrangement and move more freely. As a result, the ice melts and becomes a liquid. The process of melting involves the transition from a solid phase to a liquid phase, not a gas phase.Rate this question:

When you heat water it __________ and becomes a gas called water vapor
- A.
Precipitates
- B.
Evaporates
- C.
Condensates
Correct Answer
B. EvaporatesExplanation
When water is heated, it undergoes a process called evaporation, where it changes from a liquid state to a gaseous state, forming water vapor. This occurs because the heat energy provided to the water molecules increases their kinetic energy, causing them to move faster and break the intermolecular forces holding them together. As a result, the water molecules escape from the liquid surface and enter the air as water vapor.Rate this question:
-
- 9.
What helps water to evaporate?
- A.
Sun
- B.
Moon
- C.
Nathan H
Correct Answer
A. SunExplanation
The sun helps water to evaporate. Sunlight provides the necessary energy to break the bonds between water molecules, allowing them to escape into the air as vapor. This process is known as evaporation. The sun's heat increases the temperature of the water, increasing the kinetic energy of the water molecules and causing them to move faster. As a result, more water molecules gain enough energy to overcome the attractive forces holding them together and transform into a gaseous state.Rate this question:

______________ is when liquid water is changed to a gas called water vapor through heating
- A.
Respiration
- B.
Precipitation
- C.
Evaporation
Correct Answer
C. EvaporationExplanation
Evaporation is the process by which liquid water is converted into water vapor through the application of heat. It occurs when the energy from heat causes the water molecules to gain enough kinetic energy to break free from the liquid phase and enter the gaseous phase. This process is essential for the water cycle as it allows water to be transferred from the Earth's surface back into the atmosphere.Rate this question:
-
- 11.
___________ is the process by which gas changes to a liquid
Correct Answer
condensation
condExplanation
Condensation is the process by which gas changes to a liquid. It occurs when the temperature of a gas is lowered, causing the gas molecules to slow down and come closer together. As a result, the gas molecules lose energy and form bonds with each other, forming a liquid. This process is commonly observed when warm, moist air comes into contact with a cold surface, such as when water vapor in the air condenses on a cold window pane. Condensation is an important part of the water cycle and is responsible for the formation of clouds, rain, and other forms of precipitation.Rate this question:

______________ is when water falls back to the earth in the form of rain, snow, sleet or hail
Correct Answer
precipitation
precExplanation
Precipitation refers to the process by which water vapor in the atmosphere condenses and falls back to the Earth in the form of rain, snow, sleet, or hail. It is an essential part of the water cycle and plays a crucial role in replenishing the Earth's water resources. The term "prec" is an abbreviation for precipitation, which is commonly used in weather forecasts and discussions.Rate this question:

________________ are formed when water vapor cools and condenses on tiny solid particles of dust or smoke
- A.
Ocean tides
- B.
Snow flakes
- C.
Clouds
Correct Answer
C. CloudsExplanation
Clouds are formed when water vapor cools and condenses on tiny solid particles of dust or smoke. This process occurs in the atmosphere, where the water vapor rises and encounters these particles, causing the vapor to condense into tiny water droplets or ice crystals. These droplets or crystals then come together to form clouds, which can range in size, shape, and altitude. Therefore, clouds are the correct answer to the given question.Rate this question:
