Properties of Water

Front

What allows water molecules to bond together?

Back

Hydrogen bonds are the weak attractions between the hydrogen atom of one water molecule and the oxygen atom of another, allowing water molecules to bond together.

Front

What gives oxygen in water a slightly negative charge?

Back

Electronegativity is the tendency of an atom to attract electrons. In water, oxygen is more electronegative than hydrogen, giving it a slightly negative charge.

Front

What contributes to the surface tension of water?

Back

Cohesion is the property of water that allows water molecules to stick to each other, contributing to surface tension.

Front

What causes water to have a high surface tension?

Back

Polarity of water molecules leads to strong hydrogen bonds, which cause water to have a high surface tension.

Front

Why is water called the Universal Solvent?

Back

Water is called the Universal Solvent because its polarity allows it to dissolve many ionic and polar substances.

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding, which allows water to form droplets.

Front

Define adhesion in the context of water.

Back

Adhesion is the attraction between water molecules and other substances, allowing water to climb up surfaces like a plant's stem.

Front

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

Back

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

Front

Explain the concept of polarity in water molecules.

Back

Polarity in water molecules arises because of the unequal sharing of electrons between oxygen and hydrogen, resulting in a partial positive charge on hydrogen and a partial negative charge on oxygen.

Front

What role do hydrogen bonds play in the properties of water?

Back

Hydrogen bonds are responsible for many of water's unique properties, including its high boiling point, high specific heat, and surface tension.
