Q: Which property of polymers is primarily affected by their molecular weight?
Solution: The melting point of polymers is primarily affected by their molecular weight; higher molecular weight generally leads to higher melting points.
Steps: 6
Step 1: Understand what polymers are. Polymers are large molecules made up of repeating units called monomers.
Step 2: Learn about molecular weight. Molecular weight is the weight of a single molecule of a substance, which can vary in polymers.
Step 3: Recognize that molecular weight affects the properties of polymers. Higher molecular weight means longer chains of molecules.
Step 4: Identify the melting point. The melting point is the temperature at which a solid becomes a liquid.
Step 5: Connect molecular weight to melting point. Generally, as the molecular weight of a polymer increases, the melting point also increases.
Step 6: Conclude that the property of polymers primarily affected by their molecular weight is the melting point.
