Explain why saturated fats tend to be solids at room temperature, and cis-unsaturated fats tend to be liquids at room temperature.

1-Partial hydrogenation of (healthy) cis unsaturated fats produces trans fatty acids. Most of the trans fats produced by the hydrogentation process are classified as saturated fats even though they are still technically _______________?
2-Explain why saturated fats tend to be solids at room temperature, and cis-unsaturated fats tend to be liquids at room temperature. Think about the general 3D shape of these molecules.
3-There are several allotropes (different physical forms) of carbon in the professor’s suitcase: graphite, diamond, fullerenes, and nanotubes. The 2010 Nobel Prize for Physics was awarded for the discovery of another allotrope of carbon, which is a single sheet of graphite. What is its name?
4-Can you describe a time when collaboration worked well for you? Where there ever any disagreements that led to a false assumption (like cells spontaneously crystalizing into existence)?
5-What are the properties of water that makes life possible?
