Front

What is the polarity of water?

Back

Water is a polar molecule.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is the attraction of the hydrogen from one molecule to the oxygen of a different molecule.

Front

What makes a molecule polar?

Back

A molecule is polar due to unequal sharing of valence electrons.

Front

What unique property of water allows fish and aquatic plants to survive winter?

Back

Water expands and becomes less dense when it freezes.

Front

What property of water enables molecules to cling together in plants?

Back

Water exhibits cohesive behavior.

Front

Define cohesion in the context of water.

Back

Cohesion is the property of water that allows molecules to stick to each other.

Front

Define adhesion in the context of water.

Back

Adhesion is the property of water that allows it to stick to other substances.

Front

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

Back

Water's high specific heat allows it to absorb and release heat without significant temperature changes, moderating climate.

Front

How does water's density change when it freezes?

Back

Water becomes less dense when it freezes, which is why ice floats.

Front

What is the role of water as a solvent?

Back

Water is an excellent solvent, meaning it can dissolve many substances, facilitating chemical reactions.
