Flashcard Review: Structure and Properties of Water v2

Front

What type of bond is responsible for the cohesion between water molecules?

Back

Hydrogen bond.

Front

What is the reason sand cools down faster than ocean water after sunset?

Back

The sand has a lower heat capacity than the ocean water.

Front

What does a pH of 5.8 indicate about river water?

Back

The river water is more acidic than neutral water.

Front

How does the difference in heat absorption between land and water affect sea breezes?

Back

Sea breezes occur during the day because land heats up more quickly than water.

Front

What property allows water to exist in ice, liquid, and steam phases?

Back

Hydrogen bonding.

Front

Define cohesion in the context of water molecules.

Back

Cohesion is the attraction between water molecules due to hydrogen bonds, leading to surface tension.

Front

What is the heat capacity of a substance?

Back

Heat capacity is the amount of heat energy required to change the temperature of a substance by one degree Celsius.

Front

Explain the concept of surface tension in water.

Back

Surface tension is the elastic tendency of water's surface, caused by cohesive forces between water molecules.

Front

What is the significance of water being less dense as ice?

Back

Ice floats on water, allowing aquatic life to survive under frozen surfaces.

Front

How does water's high specific heat affect climate?

Back

Water's high specific heat helps moderate temperatures, leading to milder climates near large bodies of water.
