Answer:
Since the fatty acids in these triglycerides contain the maximum possible amount of hydrogens, these would be called saturated fats. The hydrocarbon chains in these fatty acids are, thus, fairly straight and can pack closely together, making these fats solid at room temperature. The characteristic that makes these materials solid or liquid at room temperature is the ability for the molecules to pack close together and Van der Waals forces. Oils or fats made up of mostly saturated fatty acids are able to pack very close together and produce a regular structure.
Explanation: yeah I googled this and the answers a nightmare. Oh well, I tried lol.
