Water and Aqueous Systems

Front

What is hydrogen bonding in water molecules?

Back

The attractive force between a hydrogen atom of one water molecule and an oxygen atom of another water molecule.

Front

What determines the shape of a drop of water in the absence of external forces?

Back

Surface tension.

Front

What is surface tension?

Back

The property of water in which water molecules at the surface tend to stick together.

Front

What is a result of the high surface tension of water?

Back

Water droplets forming spherical shapes.

Front

How does the structure of water contribute to its high specific heat capacity?

Back

The hydrogen bonds in water require more energy to break, stabilizing temperatures.

Front

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

Back

It helps stabilize temperatures in aquatic environments, supporting ecosystems.

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 the role of water as a solvent?

Back

Water can dissolve many substances, making it essential for biological processes.

Front

Explain the concept of density in relation to water.

Back

Water is most dense at 4°C, which is why ice floats on liquid water.
