APDE BIO Structure of Water & H Bonding

Front

What is the property of water that allows aquatic life to survive winter?

Back

Less Dense as Solid

Front

What is the significance of water being less dense as a solid?

Back

Ice floats on water, insulating the water below and allowing aquatic life to survive in winter.

Front

What property of water is responsible for evaporative cooling?

Back

Specific heat

Front

What are hydrogen bonds?

Back

Weak attractions between a hydrogen atom and an electronegative atom, such as oxygen.

Front

Where do hydrogen bonds exist in proteins?

Back

Between the backbone of the protein.

Front

What type of bond is found between water molecules?

Back

Hydrogen bond

Front

Define cohesion in the context of water.

Back

The attraction between water molecules due to hydrogen bonding.

Front

Define adhesion in the context of water.

Back

The attraction between water molecules and other substances.

Front

What is surface tension and how is it related to water?

Back

Surface tension is the cohesive force at the surface of water that allows it to resist external force.

Front

Explain the concept of specific heat in relation to water.

Back

Water has a high specific heat, meaning it can absorb a lot of heat before its temperature changes.
