Properties of Water and Their Effects

Front

What is a prokaryote cell?

Back

A prokaryote cell is a type of cell that does not have a nucleus or membrane-bound organelles. Examples include bacteria.

Front

What is the cell theory?

Back

The cell theory states that: 1) All living things are made of cells, 2) Cells are the basic unit of life, 3) All cells come from preexisting cells.

Front

What is capillary action?

Back

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces, such as when water moves up a plant stem.

Front

What type of bond forms between two water molecules?

Back

A hydrogen bond forms between two water molecules.

Front

What type of bond exists between the hydrogen and oxygen atoms in a water molecule?

Back

A polar covalent bond exists between the hydrogen and oxygen atoms in a water molecule.

Front

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

Back

Water's high specific heat allows it to absorb a lot of heat without a significant change in temperature, helping to regulate climate and maintain stable environments.

Front

What is surface tension in water?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane, allowing small objects to float.

Front

What is the role of water as a solvent?

Back

Water is known as the 'universal solvent' because it can dissolve many substances, facilitating chemical reactions in biological systems.

Front

What is the importance of ice floating on water?

Back

Ice floats on water due to its lower density, which insulates the water below, protecting aquatic life during cold temperatures.

Front

What is cohesion in water?

Back

Cohesion is the attraction between water molecules, which allows for phenomena like water droplets forming and surface tension.
