### What is the process by which a liquid changes to a gas?

• A.

Evaporation

• B.

Condensation

• C.

Precipitation

• D.

Deposition

A. Evaporation
Explanation
Evaporation is the process by which a liquid changes to a gas. It occurs when the molecules of a liquid gain enough energy to break their intermolecular bonds and escape into the air as vapor. This process usually happens at the surface of the liquid, where the molecules with the highest energy can escape. Evaporation is influenced by factors such as temperature, surface area, and the presence of air currents. It is an important part of the water cycle and plays a crucial role in cooling processes, such as sweating, as well as in the formation of clouds and rain.

### What is the process when gas changes back into a liquid?

• A.

Precipitation

• B.

Evaporation

• C.

Condensation

• D.

Deposition

C. Condensation
Explanation
Condensation is the process when gas changes back into a liquid. This occurs when the gas molecules lose energy and slow down, causing them to come closer together and form liquid droplets. This can happen when the temperature of the gas decreases or when the gas comes into contact with a cool surface. Condensation is a common natural phenomenon, seen for example when water vapor in the air condenses to form clouds or when steam from a hot shower condenses on a mirror.

• E.

They are a type of cloud

A. They are also called Twisters
B. Occur in Midwestern US
Explanation
Tornadoes are commonly referred to as twisters and they do indeed occur in the Midwestern US. The term "twister" is often used to describe the twisting motion of a tornado as it forms and moves across the land. The Midwestern US, also known as Tornado Alley, experiences a higher frequency of tornadoes due to the unique combination of warm, moist air from the Gulf of Mexico colliding with cool, dry air from the Rockies. This creates the ideal conditions for tornado formation.
