Water Changing State and Water Cycle ~ Study Guide [Review 2023 ~ Team E]

evaporation [boiling]

Which type of change occurs when the starting state is a liquid and the ending state is a gas? This happens around 100 degrees Celsius.

condensation

Which type of change occurs when the starting state is a gas and the ending state is a liquid?

Evaporation

______________ occurs as water molecules absorb energy and it occurs at the surface of a liquid. Water is changing from a liquid to a gas.

An example of ___________ is air drying your wet hair.

Condensation

________________ occurs as water molecules slow down changing from a gas to a liquid.

An example is when your breath clouds up a cold window.

precipitation

Water that falls to the Earth as rain, snow, sleet, or hail is called ______________. Water is returned to the Earth's surface from the atmosphere.

Water

____________ is the only substance on Earth that commonly exists in all of its different states (solid, liquid, or gas).

3%

The percentage of the Earth's water that is fresh water is ______?

97%

The percentage of the Earth's water that is salt water is ______?

sun

The energy for the water cycle originally comes from the ____________.

water cycle

Water that falls to the Earth as rain, snow, sleet, or hail is called the ______________. Water is returned to the Earth's surface from the atmosphere.

evaporation

The four factors that affect the rate (speed) of ___________ are temperature, surface area, humidity, and wind speed.

increases

The rate of evaporation ______________ with an increase in temperature. The water molecules move faster and spread out more during evaporation.

slower

The water molecules move _________ and come closer together during condensation.

decreases

The amount of water vapor present in the air is called humidity. The rate of evaporation ____________ with an increase in humidity.

increases

The rate of evaporation ______________ with an increase in surface area.

increase

Evaporation increases with an ______________ in wind speed.

water cycle

The process(es) of evaporation, precipitation, and condensation are involved with the _____________.

sublimation

Water changes from a solid to a gas by skipping over the liquid phase.

Examples of __________: dry ice and solid air fresheners.

transpiration

The evaporation of water through the plant's leaves, stems and flowers in the form of water vapor is referred to as _________.

cool down

When water molecules ________ ________, the molecules move slower and closer together.

32°F or 0°C

The freezing point of water is __________.

lowers

Salt ____________ the freezing point of water, so the surface temperature is much colder [less than the normal freezing point 32°F or 0°C] before it could freeze.

212°F or 100°C

The boiling point of water is _________.

gravity

In the water cycle, _________ causes water to flow downward on land. It causes rain, snow, and hail to fall from clouds to the ground. Lastly, it pulls water into the ground.
