does anybody here know the freezing point of coooking oil and the boiling point of mercury?

Question

what are their values?

Answer 1

cooking oil dosent freeze

When the molecules in a liquid line up into a very regular pattern (a crystal), we say that they freeze. This type of process happens at a sharply defined freezing temperature. Vegetable oil consists of molecules in long chains called lipids, usually with a mixture of molecules of different sizes and shapes. That makes it hard for the oil to form a regular crystal, suppressing ordinary freezing. There are exceptions, however, such as cocoa butter, which freezes at 34 °C.

Cooling down oil does make it resist flow however, becoming more "viscous". Eventually, if you get it cold enough, the oil will seem to be quite solid, as the molecules lose the energy needed to move around. In that sense, you can say that oil does in fact freeze, but it has not sharply defined freezing point, like water. Glass is similar, in that it gets soft and eventually quite fluid as it is heated, but there is no one sharp melting temperature. The molecules get stuck when cold, but not in any simple regular arrangement.

The boiling point of Mercury is 356.58 º C

Answer 2

Mercury is an element, which means that its freezing point is a well-known property. That is to say, you can find it by running any internet search (eg. Google) in about as much time as it took you to post your question to this forum.

Cooking oil on the other hand is not an element or unique chemical substance. Too many substances (eg. olive oil, peanut oil, soya oil, etc.) and their mixtures come under the general designation cooking oil. They have their own freezing points which can be found easily and quickly through an internet search. As a general rule of thumb, cooking oils freeze easier the closer they are to saturation (if you know what this means). Thus butter (which is solid at room temperature) freezes before olive oil does (at temperatures close to but higher than zero degrees C), which in turn freezes before lighter oils (eg. corn oil) freeze.

Answer 3

Boiling point of mercury is 357 degree C Sunflower oil will apparently freeze at -17 C

Answer 4

Freezing point of Cooking oil varies with brands and composition.

Mercury boils off somewhere near 200 degrees Celsius.
