saturated fats (butter) tend to be solid at room temperature whereas monounsaturated and polyunsaturated fats do not (mustard oil is a mixture of mono- and polyunsaturated fats)
The difference in the physical states of butter and mustard oil at room temperature is due to their different compositions of fats and oils. Butter contains a higher proportion of saturated fats which are solid at room temperature, while mustard oil is mainly composed of unsaturated fats which are liquid at room temperature. The structure and arrangement of the fat molecules in each substance determine their physical state.
Liquid
Yes, butter can be a liquid when it is melted. At room temperature, butter is typically solid. Heating butter to a temperature above 95°F (35°C) will cause it to melt and become a liquid.
Because the butter goes from being a solid to a liquid as it changes temperature.
it is a liquid
Solid if it's cold, liquid if it's heated.
No, they are not. Butter will not go liquid at room temperature, unless it's in a hot room. (In most moderate room temperatures it is still solid). Lard melts an an even higher temperature than butter. Generally it's animal fats that are solid at room temperature.
"Butter" is a fat that is solid at cold and cool temperatures but melts into a liquid at warm and hot temperatures. It really depends on what you mean by butter. There is two types of butter; Spray butter, and the stick butter. The spray is a liquid, and the stick is a solid.
Butter is a solid. By definition of a solid, butter has a definite shape and a definite volume.
Peanut butter is a solid. By definition of a solid, peanut butter has a definite shape and a definite volume.
Cocoa butter is solid at room temperature.
Well, if the butter is melted - it's a liquid. The process of a liquid becoming a solid is called "Solidification" So, in your case, it's called "Butter Solidification"
