Unit 5 Water Review

Front

What is the process of evaporation in the water cycle?

Back

Evaporation is the process where liquid water is transformed into water vapor, usually due to heat from the sun.

Front

Why can fish live in frozen lakes?

Back

Fish can live in frozen lakes because water is less dense as a solid than as a liquid, allowing liquid water to remain below the ice.

Front

What property of water allows it to dissolve many substances?

Back

Water is a polar molecule, which means it has a positive and a negative end, allowing it to interact with and dissolve various substances.

Front

What is surface tension?

Back

Surface tension is the property of the surface of a liquid that allows it to resist external forces due to the cohesive nature of water molecules.

Front

What indicates a phase change in water?

Back

A decrease in the water level in a glass indicates that water is undergoing a phase change, such as evaporation.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water molecules sticking together due to hydrogen bonding, which contributes to surface tension.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat means it can absorb a lot of heat without a significant change in temperature, helping to regulate climate.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, which is why ice floats on liquid water.

Front

What is the role of water as a solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid, making it essential for life.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, including processes like evaporation, condensation, and precipitation.
