Question: At what general temperature range do fats typically exist as solids?
Options:
10°C
Varies depending on the fat (10°C to 40°C)
30°C
40°C
✅Explanation: The temperature at which fats exist as solids depends on their composition and type. Fats are primarily made up of triglycerides, and their melting point is influenced by factors such as:
-Saturation: Saturated fats (e.g., butter, lard) have higher melting points and are more likely to be solid at room temperature.
-Chain length: Longer fatty acid chains generally increase the melting point.
-Unsaturation: Unsaturated fats (e.g., olive oil, canola oil) have lower melting points due to double bonds creating kinks in the structure, making them liquid at room temperature.

-Unsaturation: Unsaturated fats (e.g., olive oil, canola oil) have lower melting points due to double bonds creating kinks in the structure, making them liquid at room temperature.
• Fats solidify over a wide range of temperatures depending on their type. For example:
-Butter: solid at ~20°C but melts at ~32°C.
-Coconut oil: solid below ~24°C but melts above this temperature.
