2. Comparing the Thermal Properties of Methane and Water
Methane and water are both small molecules that have a similar molecular mass. Despite this, they have very different thermal
properties. This is a result of hydrogen bonds forming between water molecules. Because methane is not polar, hydrogen bonds
do not form. As a result, methane has much weaker intermolecular forces (the forces that hold molecules together) than water.
1. Find diagrams of the atomic structure of both methane and water:
Methane Water
2. Describe and compare their molecular structures. What is similar, and what is different?
