What happens to water molecules during evaporation?

• They become heavier

• They lose kinetic energy

• They form stronger bonds

• They gain kinetic energy and escape into the atmosphere

What is the effect of condensation in the water cycle?

• It releases energy and forms liquid droplets

• It absorbs energy and forms gas

• It decreases atmospheric pressure

• It creates thermal pollution

How does the sun influence the water cycle?

• It provides energy that drives evaporation

• It prevents evaporation

• It increases water salinity

• It decreases water temperature

Why does water have a smaller temperature change compared to sand when both receive the same amount of energy?

• Water stores more energy internally

• Sand absorbs less energy

• Water reflects all heat

• Sand is a better heat conductor

Why does water not increase in temperature as much as sand when heated?

• It is less dense

• It evaporates completely

• It has higher specific heat capacity

• It is more reflective

At what temperature is water most dense?

• 100° C

• 0° C

• 4° C

• 10° C

How does the density of water affect aquatic life in lakes during winter?

• It decreases oxygen levels drastically

• It increases water toxicity

• It allows ice to form on the surface, insulating the water below

• It causes all water to freeze

What is the significance of hydrogen bonding in water?

• It makes water a gas at room temperature

• It makes water non-polar

• It allows water to remain liquid at room temperature

• It prevents water from being used by organisms
