Properties of Water

Front

What is the process of changing liquid water into water vapor?

Back

Evaporation is the process of changing liquid water into water vapor when heat is added.

Front

What happens to water when it is heated?

Back

When water is heated, it can change from a liquid to a gas (water vapor) through evaporation.

Front

What is condensation?

Back

Condensation is the process by which a gas changes back into a liquid when heat is taken away.

Front

What is the freezing point?

Back

The freezing point is the temperature at which a liquid changes into a solid when heat is taken away.

Front

What is a constant in scientific experiments?

Back

A constant is a factor that does not change or vary during an experiment.

Front

What is the boiling point of water?

Back

The boiling point is the temperature at which water changes from a liquid to a gas.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of liquid turning into gas, while condensation is the process of gas turning back into liquid.

Front

What is an example of a physical change in water?

Back

An example of a physical change in water is when ice melts into liquid water.

Front

What happens to water molecules during evaporation?

Back

During evaporation, water molecules gain energy and move apart to become water vapor.

Front

What is the role of heat in changing the state of water?

Back

Heat is required to change water from a liquid to a gas (evaporation) and is removed to change it from a gas to a liquid (condensation).
