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.

Explanation:
Underclass represent a section of the population who inhabits the lowest position in the class system of social order. They are below the working class as they find it hard to find stable jobs with steady income.
Compared to the working class, the underclass section of the population are exploited less. They are usually perceived to be less productive because of lack of education and skills. Thus, they are exploited less by the higher classes because of their incapacity to be productive. Instead, the working class, though higher than the underclass in the class ladder, is being exploited more because of their productivity.
In case of Tom, who belongs to the underclass section, despite having some earnings, he depends on government programs to make ends meet because his chances of being recruited into a stable job is very minimal.
