Saturated fats and trans-fats are solid at room temperature. Polyunsaturated and monounsaturated fats (oils) are liquid at room temperature.
Trans-fats are liquid fats that are treated chemically and thermally to mimic saturated fats, usually in a process called hydrogenation. This process in a nutshell (it's a bit more complicated) injects hydrogen into the oils at high temperature and high pressure producing polymers (plastics) from the hydrocarbon molecules in the oils. Most vegetable shortenings are produced this way, shortenings (solid fats) that are not natural saturated fats are trans-fats.
saturated triglycerides tend to be hard at room temperature because they come primarely from animals
Saturated fats are most likely to be solid at room temperature.
Animal fats are lipid materials, both oils and fats. Fats and oils are both made up of triglycerides. Oils are liquid at room temperature and fats are solid.
Calcium is a solid metal element at room temperature. It is found in group 2 of the periodic table and has a silvery appearance.
Saturated fats tend to be solids at room temperature. This is because the hydrocarbon tails of saturated fat molecules are straight, due to the lack of double bonding between carbon atoms. As a result, the saturated fat molecules are more compact, allowing them to exist as solids at lower temperatures. Examples: butter and lard.
Marble is a solid at room temperature. It is a type of metamorphic rock that forms from the recrystallization of limestone under high pressure and temperature.
Any sort of vegetable oil is usually liquid at room temperature.
Carbon is a solid at room temperature. Not a gas.
Triglycerides are the type of lipid that stores extra energy and is liquid at room temperature. They consist of a glycerol molecule and three fatty acid chains.
The type of fatty acids in the triglycerides, the amount of water present and if food additives are present.
Granite is clearly a solid at room temperature.
depending on the oil it has like Lard.
