Water and Inorganic Chemistry

There are partial charges within a water molecule which cause water to have special properties. This makes water a ________ molecule.

• Polar

• Nonpolar

• Hydrophobic

• Ionic

Bonds that hold a water molecule together (inside 1 water molecule) are called ____________.

• Covalent Bonds

• Ionic Bonds

• Hydrogen Bonds

• Water Bonds

Weak attractions between MULTIPLE water molecules are called ____________.

• Hydrogen Bonds

• Covalent Bonds

• Ionic Bonds

• Water Bonds

When water rises up a thin straw or moves up a tree from the roots to the leaves, it is called _____________.

• Capillary Action

• Surface Tension

• Heat of Vaporization

• Density of Water

Water is liquid at room temperature and takes a lot of energy (heat) to reach the boiling point and turn to a vapor. What is this called?

• Heat of Vaporization

• Cohesion

• Heat of Fusion

• Surface Tension

Very light insects can sit on top of water because of

• Water's High Heat of Vaporization

• Surface Tension

• Water's High Specific Heat

• Capillary Action

Why does ice float?

• As water freezes, the molecules move farther apart (expands) and the density decreases.

• As water freezes, the hydrogen bonds mix with air and create buoyancy.

• As water freezes, the bonds break, making it float.

• As water freezes, the molecules move closer together, causing the density to increase.

What makes water a universal solvent?

• It is a polar molecule that can form hydrogen bonds, allowing it to dissolve many substances.

• It is a nonpolar molecule that can form hydrogen bonds, allowing it to dissolve many substances.

• It is a polar molecule with a low specific heat, allowing it to dissolve many substances.

• It is a nonpolar molecule with a low specific heat, allowing it to dissolve many substances.

When it rains, water will stick to your clothes and get them wet. What property is this an example of?

• Cohesion

• Adhesion

• High Specific Heat Capacity

• Surface Tension

What property allows water molecules to stick to each other to form drops?

• Cohesion

• Adhesion

• Surface Tension

• Capillary Action
