Properties of Water

Polarity

Uneven distrubuting of charges across a molecule making one end positive (H) and one negative (o)

Cohesion

Water molecules to form weak bonds and stick to each other.

Adhesion

Tendency of water to stick to other substances.

Capillary Action

Adhesion and Cohesion allow water to move in a continuous column from a plant's roots to leaves this an upward movement.

Surface tension

A force that acts on particles of a liquid at the surface

Specific heat

The amount of heat needed to increase the temperature of other substances.

Hydrogen Bond

Bonds that from water molecules.

Bonds that are formed between water molecules are called______bonds

Hydrogen

True or False? Hydrogen bonds are strong and require a lot of energy to break.

False

How does surface tension force the surface of water to curve?

The molecules are attached to each other, not the air which pulls them in.

What is a curved surface in a graduated cylinder called?

Meniscus

How does capillary action allow water to climb up the sides of a straw?

The water molecules use adhesion and cohesion.

A mixture that forms when one substance dissolves another is called?

Solvent

Why can water dissolve many substances?

Because of its polarity.

A substance that hates, or “fears” water is called

Hydrophobic

True or False? Compared with other substances, water requires a lot of heat to increase its temperature.

False.

How does the high specific heat of water affect your body?

It helps regulate your body temperature.
