Long,
saturated fatty acids
are most likely to be solid at room temperatures; therefore, Choice b is the correct answer.
What is most likely solid at room temperature?
Fluorine, chlorine, nitrogen, and oxygen are all gases as they all have diatomic molecules without strong intermolecular forces. Bromine is liquid, and carbon,
phosphorous, sulfur, and selenium
are solid at room temperature.
Which fatty acid would be the most solid at room temperature?
Trans-unsaturated fatty acids
can pack more tightly and are more likely to be solid at room temperature. Some types of shortening, for example, contain a high fraction of trans fats 3. Partial hydrogenation and trans fats might seem like a good way to get a butter-like substance at oil-like prices.
Which lipids are solid at room temperature?
Those molecules that are usually solid at room temperature (plant or animal) are termed
fats
, while those that are liquids at room temperature are termed oils. These latter are usually found in plants, but fish also store liquid forms of triglycerides (fish oils).
Do oils get solid at room temperature?
Solid fats mainly come from animal foods. Oils are fats that are
liquid at room temperature
, like canola or olive oil. Oils come from many different plants and from fish. However, coconut, palm, and palm kernel oils (tropical oils) are solid at room temperature because they have high amounts of saturated fatty acids.
Which metal is not solid at room temperature?
Mercury
is a metallic chemical element that is an only metal that is not a solid at room temperature.
Is in solid state at a room temperature?
The state a given substance exhibits is also a physical property. Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids.
Most metals
exist as solids at room temperature. All substances can exist in any of these three states.
Is body fat solid or liquid?
Fats are
liquid or solid
according to their chemical make up or how their building blocks are stacked together. Imagine a tower of tightly stacked blocks. The close packing of these blocks is similar to the tightly packed molecules that make saturated fats appear solid.
Why are some fatty acids solid at room temperature?
Saturated fats are solid at room temperature
due to their molecular shape
. … This change in structure will cause the fat molecules to not stack very well resulting in fats that are liquid at room temperature. Butter is mostly saturated fat, that’s why it’s solid at room temperature.
What is the room temperature?
The American Heritage Dictionary of the English Language identifies room temperature as around
20–22 °C (68–72 °F)
, while the Oxford English Dictionary states that it is “conventionally taken as about 20 °C (68 °F)”.
Which type of fat is solid at room temperature quizlet?
At room temperature,
saturated fats
(such as those commonly found in butter and other animal fats) are solid, whereas unsaturated fats (such as those found in vegetable oils) are usually liquid.
Which molecules are solid at room temperature?
From left to right:
quartz
(solid), water (liquid), nitrogen dioxide (gas). The state a given substance exhibits is also a physical property. Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids.
Which of the following lipids are not solid at room temperature?
The molecular structure of
unsaturated fats
makes them liquid at room temperature. Their fat molecules do not stack easily, so they cannot form a solid at this temperature.
Is coconut oil a solid or liquid at room temperature?
All Coconut oil is made up of a number of different fatty acids, all of which have their own distinct melting points. The fatty acids with higher melting points are the reason
regular coconut oil is solid at room temperature
(approximately 68 degrees F).
Why fat is solid and oil is liquid at room temperature?
Both fats and oils are molecules shaped like a capital E with a glycerol spine and arms made of fatty acid chains. In animals, the carbon atoms in the fatty acids are saturated with hydrogen atoms. … This reduces the amount of
intermolecular bonding
that can occur and keeps the molecules liquid at room temperature.
Why is butter solid at room temperature but mustard oil is not?
Answer: Butter is
about two-thirds saturated fat
; mustard oil is mostly unsaturated. … Butter, which has more saturated fat than mustard oil, is therefore solid at higher temperatures than mustard oil.
