According to the Indian Institute of Science, Bangalor, oil is the general term that applies to all liquid lubricants, while greases are oils that have been mixed with a thickening agent, which turns them into a semi-solid material. Rather than imparting additional lubrication to the mixture, the thickening agent holds the lubricating oil while reducing its viscosity.Continue Reading
Greases and oils both lubricate similar materials, but some applications favor one type over the other. For example, oil is easy to pour, which makes it convenient to use in car engines. Additionally, as the oil gradually undergoes chemical changes while lubricating the engine and collects bits of debris, it must be replaced periodically. This is easier to accomplish with a liquid that can be drained easily, as opposed to a grease, which does not flow well.
By contrast, greases are better suited for applications dealing with sealed containers or components that are hard to access. For example, bearings and gears frequently rely on grease as a lubricant, rather than oil. Unlike oil, greases do not carry heat away from moving parts and are unsuitable for use as a coolant. Additionally, because grease does not transport heat well, it is used in lower-speed applications than oils are. Eventually, most greases turn into a full liquid or a hard deposit.Learn more about Organic Chemistry
Some differences between kerosene and other combustible oils are its price, which can be significantly higher than other oils, the possible addition of fragrances or deodorants to the product and a specific gravity, or relative density to water, which is less than other fuel oils except gasoline. Kerosene's heating value, or heat content, is 135,000 British thermal units, or BTUs, per gallon, compared to number 2 fuel oil's 139,400 BTUs per gallon rating, but kerosene's heat content is greater than 43,000 BTUs per gallon compared to propane gas.Full Answer >
Some tips for cleaning leather coats include testing a cleaning agent in an inconspicuous spot; buffing the soap used for cleaning; using rubbing alcohol, lemon juice, vinegar, cream of tartar, and linseed oil to remove mold, spots and road salt; and using leather conditioner to keep the material supple. In addition, clean the coat regularly, and remove spots and molds as soon as possible.Full Answer >
Cellulose gum is a common thickening agent made from the cell wall of plants and wood used in many modern foods. The substance is found in a variety of food products, ranging from breads to dairy items. Food manufacturers like it for its texture, protein stabilization and moisture retention.Full Answer >
