- 1.
Density of most oils and fats to compare with water is?
- A.
Equal
- B.
lower
- C.
higher
Correct Answer
B. lowerExplanation
Most oils and fats have a lower density compared to water. This means that oils and fats are less dense and will float on top of water. This is due to the fact that oils and fats are composed of nonpolar molecules, which do not mix well with the polar molecules in water. The difference in density allows oils and fats to separate from water, forming distinct layers.Rate this question:

Proteins
- B.
Sacharids
- C.
Vitamines
- D.
lipids
Correct Answer
D. lipidsExplanation
Oils are biologically classified as lipids. Lipids are a diverse group of molecules that include fats, oils, and waxes. They are characterized by their insolubility in water and solubility in organic solvents. Oils, specifically, are a type of lipid that are liquid at room temperature. They are primarily composed of triglycerides, which consist of glycerol and three fatty acid chains. Oils play important roles in energy storage, insulation, and the formation of cell membranes.Rate this question:

untrans fats
Correct Answer(s)
A. Suturated fats
B. Unsuturated fats
C. trans fatsExplanation
Fats are divided into different categories based on their chemical structure and properties. Saturated fats are fats that consist of saturated fatty acids and are typically solid at room temperature. Unsaturated fats, on the other hand, contain unsaturated fatty acids and are usually liquid at room temperature. Trans fats are a type of unsaturated fat that are created through a process called hydrogenation, which makes them more solid and stable. Untrans fats is not a recognized category of fats, so it is not a correct answer.Rate this question:

difference between flash point and smoke point is
- A.
fat or oil combusts when reaching smoke point
- B.
Smoke point is when fat/oil starts to break down and release free radicals and acrolein
- C.
flash point is same between oils but different between fats
- D.
flash point is temperature when most of the deep frying happens while smoke point is when most of the confiing happens
Correct Answer
B. Smoke point is when fat/oil starts to break down and release free radicals and acroleinExplanation
The smoke point refers to the temperature at which fat or oil starts to break down and release free radicals and acrolein. It indicates that the fat or oil is no longer stable and can potentially produce harmful substances when heated further. On the other hand, the flash point is the temperature at which the fat or oil can ignite and sustain combustion. While the flash point may be the same for different oils, it can vary between fats. The flash point is important in deep frying as it indicates the temperature at which the frying process occurs, while the smoke point is more relevant to the process of confining.Rate this question:

If oil or fat catches on fire, which fire extinguisher you have to use?
- A.
Water (red)
- B.
CO2 (black)
- C.
Wet chemical (yellow)
- D.
Foam (beige)
- E.
Dry powder (blue)
Correct Answer
C. Wet chemical (yellow)Explanation
Wet chemical fire extinguishers are specifically designed to tackle fires involving oil or fat. When oil or fat catches fire, it can be difficult to extinguish with water as it can cause the fire to spread or create a steam explosion. Wet chemical extinguishers contain a special solution that reacts with the oil or fat, creating a soapy foam that cools and smothers the fire. This makes wet chemical extinguishers the most effective choice for dealing with oil or fat fires.Rate this question:
