Earth's Systems and Properties of Water Study Guide

A substance into which the solute dissolves is called a_______.

• solvent

• solution

• solute

A substance that is being dissolved is called a______.

The word that describes when water is attracted to other substances is called_____.

Why can water have no net charge but slight charges in different molecular parts?

• The oxygen end is slightly negative, and the hydrogen end is slightly positive.

• The hydrogen end is slightly negative, and the oxygen end is slightly positive

• The hydrogen and oxygen ends change in polarity.

• Because it is hydrophobic

The attraction that causes water and other liquids to form drops on thin films is called ________________. This is also water’s ability to be attracted to other water molecules.

• adhesion

• Capillary action

• cohesion

• surface tension

Large bodies of water help to keep nearby climates from being too hot or too cold because they...

• absorb heat in the spring and slowly release that heat in the fall.

• absorb heat in the fall and slowly release that heat in the spring.

• absorb heat in the summer and slowly release that heat in the winter.

• absorb heat in the winter and slowly release that heat in the summer

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes.

• Capillary action pulls the water molecules like a chain.

• Water is pulled by gravity

• Water's cohesion causes it to pull towards the leaves

• Adhesion

• Cohesion

• Specific heat capacity

• pH

• True

• False
