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.
I turns hard like if you leave all the way melted butter at room temperature
A fat can be a solid or a liquid. Normally we refer to a liquid fat as an 'oil', but this is for a fatty compound that is liquid at room temperature. All fats can be liquified or solidified, and will still be called 'fats' no matter what.
Saturated. Saturated Fats are solid at room temperature (like butter), whereas Unsaturated fats are liquid at room temperature (like Vegetable oils).
no
no. Mercury is a liquid at room temperature under 1 atmosphere. And hydrogen, technically, is also a metal.
It means whether the substance in question is solid, liquid or gas at normal room temperature, so you could assume that about 20 degrees celsius. Oxygen is a gas at room temperature Water is a liquid at room temperature Iron is a solid at room temperature.
liquid as in thermometers
You have one or more double bonds between carbon atoms in unsaturated fat molecules. You have no such double bonds in the structure of saturated fat molecules. You have all the single bonds between the carbon atoms.
no not all metallic are solid at room temperature.
Oils are extracted from plants/nuts/seeds, whereas fats can come from animals (but don't have to). All oils are fats, but not all fats are oils. "Fats" is just the name given to group of ingredients where their primary constituent (nutritionally) is fat.
ALL liquid substances at room temperature become gaseous at higher (sometimes much higher) temperature called boiling point, unless they decompose at lower temperature.
None of them are Fluorine, Chlorine and Bromine are all gases at room temperature. Iodine and Astatine are both solid at room temperature.
