Properties of Water

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is a substance with a pH greater than 7 called?

Back

A substance with a pH greater than 7 is called a Base.

Front

What are the attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule called?

Back

These attractions are called Hydrogen bonds.

Front

Describe the process of diffusion in terms of concentration.

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What charge do the hydrogen atoms in a water molecule carry?

Back

The hydrogen atoms in a water molecule are positively charged.

Front

What is the chemical formula for water?

Back

The chemical formula for water is H2O.

Front

What is polarity in water molecules?

Back

Polarity in water molecules refers to the uneven distribution of electron density, resulting in a partial positive charge on hydrogen atoms and a partial negative charge on the oxygen atom.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds are significant in water because they contribute to water's unique properties, such as high surface tension, high specific heat, and the ability to dissolve many substances.

Front

What is cohesion in the context of water?

Back

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

Front

What is adhesion in the context of water?

Back

Adhesion is the property of water that allows it to stick to other substances, which is also due to hydrogen bonding.
