Evaporation of water

Front

What is evaporation?

Back

Evaporation is the process where water changes from a liquid to a gas and goes into the air.

Front

What happens to water when it evaporates?

Back

When water evaporates, it turns into water vapor and rises into the air.

Front

What do we call the water vapor that is in the air?

Back

The water vapor in the air is called humidity.

Front

What can make water evaporate faster?

Back

Water can evaporate faster when it is warm, has more air movement, or has a larger surface area.

Front

What is the effect of temperature on evaporation?

Back

The higher the temperature, the faster the rate of evaporation.

Front

How does air movement affect evaporation?

Back

Faster air movement increases the rate of evaporation.

Front

What happens to water molecules during evaporation?

Back

Water molecules on the surface obtain energy to move faster and escape into the air.

Front

What is surface area in relation to evaporation?

Back

Surface area is the amount of water exposed to air; a larger surface area leads to faster evaporation.

Front

What is an example of evaporation?

Back

An example of evaporation is when a puddle of water dries up on a sunny day.

Front

Can water evaporate in cold temperatures?

Back

Yes, water can still evaporate in cold temperatures, but it happens more slowly.
