Explanation:
→ <u>Independent Variable</u>:
- The variable you change on purpose, to see certain effects.
- Doesn't depend on other variables.
- Usually the time.
→ <u>Dependent Variable</u>:
- Usually the reaction based on the independent variable.
- Refers to Independent Variable.
- The result or the experiment.
→ <u>Control Group</u>:
- Is the constant variable in all test.
- Usually is the one with
changes.
→ <u>Experimental Group</u>:
- The treatment group.

A way to prevent spoilage of unsaturated fats and make them solid at room temperature is to change their fatty acids chemically through: Hydrogenation.
- Hydrogenation is a chemical reaction between molecular hydrogen and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds.
- Hydrogenation reactions are extensively used to create commercial goods.
- Hydrogenation is used in the food industry to make a large variety of manufactured goods, like spreads and shortenings, from liquid oils. This process also increases the chemical stability of products and yields semi-solid products like margarine.
- Hydrogenation is also used in coal processing. Solid coal is converted to a liquid through the addition of hydrogen. Liquefying coal makes it available to be used as fuel.
