Microwave ovens work by causing polar molecules (for example, the water in foo to rotate. The food is heated as the water molecules are caused to spin around and bump into each other. Could a microwave oven be used to heat a sample of a mixture of oils (CH3, C&H18, and C12H26)? Explain your response.

### Understanding How Microwave Ovens Work

Microwave ovens work by causing polar molecules (for example, the water in food) to rotate. The food is heated as the water molecules are caused to spin around and bump into each other.

### Application to Oils

**Question:**
Could a microwave oven be used to heat a sample of a mixture of oils (CH₃, C₈H₁₈, and C₁₂H₂₆)? Explain your response.

**Explanation:**
Microwave ovens primarily heat substances that contain polar molecules. Water is a good example of a polar molecule, which is why foods with high water content heat well in microwaves. Conversely, oils, like those mentioned (CH₃, C₈H₁₈, and C₁₂H₂₆), are non-polar. Therefore, they do not absorb microwaves effectively, making the heating process less efficient in microwave ovens compared to substances with polar molecules.
