Water Chemistry

Front

What type of bond holds a water molecule together?

Back

Polar covalent bond.

Front

What is the term for the property of water molecules being attracted to other water molecules?

Back

Cohesion.

Front

Why do coastal cities like San Diego have a smaller air temperature range than inland cities?

Back

The high heat capacity of water allows the ocean to moderate the temperature of nearby air and land.

Front

Why is water considered a universal solvent?

Back

Because it dissolves most substances.

Front

What property of water is described by the fact that ice is less dense than liquid water?

Back

Water is less dense as a solid than as a liquid.

Front

What is the term for the attraction between water molecules and other substances?

Back

Adhesion.

Front

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

Back

It allows water to absorb and release large amounts of heat without significant temperature changes.

Front

What is surface tension in water?

Back

The cohesive force between water molecules at the surface, allowing it to resist external force.

Front

How does water's polarity contribute to its solvent properties?

Back

Water's polarity allows it to surround and interact with various solutes, facilitating their dissolution.

Front

What is the effect of temperature on the density of water?

Back

Water is most dense at 4°C; as it cools further to freezing, it becomes less dense.
