Is melting a fat a chemical change?
No, melting (of anything) is always physical. The reverse proces is easily done: freezing
Is burning fat a chemical change?
Yes, burning fat is a chemical change. During the process of combustion, fat molecules react with oxygen to produce carbon dioxide and water, resulting in a transformation of the substance's chemical structure. This change is not reversible, as the original fat cannot be recovered once it has been burned.
Is making of soap from lye and fat a chemical change or physical change?
physical
How many kilojoules body fat is in a kilogram body fat?
Approximately 37,656 kilojoules of energy are stored in a kilogram of body fat. This represents the potential energy that can be released by metabolizing that amount of fat.
Why is churning a chemical change?
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
Is 'fat' solidifying in a chip pan is it a chemical reaction?
No, the fat solidifying in a chip pan is a physical change, not a chemical reaction. The change from liquid fat to solid fat is due to the cooling of the fat, not a chemical transformation.
Does bile bring about a chemical or physical change to fat?
Bile will bring about a chemical change to fat. This is because bile chemically alters the way the fat is structured.

Is melting lard a chemical change?
No, it is a physical change because the chemical composition of the fat molecules are not changing.
Is making of soap from lye and fat a chemical change or physical change?

Is breaking down of large fat droplets into small fat droplets by bile a physical or chemical change?
physical change
Is changing the oil in a deep fat fryer a chemical change?
yeap.
Do sodium hydroxide dissolve fat grease and hair in a drain and is it a physical change or chemical change?
Yes, sodium hydroxide dissolves fat, grease, and hair in a drain by converting them into soap which can be washed away easily. This process involves a chemical change as sodium hydroxide reacts with the substances to break them down into different chemical compounds.
Is vitamin B12 good for dieting?
Yes! B12 is essential for metabolizing fat. (so is good hydration)
How many kilojoules body fat is in a kilogram body fat?
Approximately 37,656 kilojoules of energy are stored in a kilogram of body fat. This represents the potential energy that can be released by metabolizing that amount of fat.
Is fat solidifying in a chip pan a chemical reaction?
Yes, this is a chemical reaction in the sense that a lowering of the temperature causes fat to move from a more liquid form to a more solid form.
