Is melting a fat a chemical change?
Melting fat is a physical change, not a chemical change. When fat melts, it changes from a solid to a liquid state without undergoing a chemical reaction. The molecules in the fat remain the same.
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?
Churning is not a chemical change, but a physical change. It involves breaking up larger molecules, like fat globules in milk, into smaller ones through mechanical action, without altering their chemical composition. Chemical changes involve the formation of new substances with different chemical properties.
Which organs help in the chemical and physical change of fat?
The liver, pancreas, and small intestine are involved in the chemical and physical changes of fat in the body. The liver produces bile, which helps break down fat globules into smaller droplets. The pancreas releases enzymes that further break down the fats into absorbable molecules in the small intestine.
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 a fat a chemical change?
Melting fat is a physical change, not a chemical change. When fat melts, it changes from a solid to a liquid state without undergoing a chemical reaction. The molecules in the fat remain the same.
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?
physical
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.
Is vitamin B12 good for dieting?
Yes! B12 is essential for metabolizing fat. (so is good hydration)
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 fat solidifying in a chip pan a chemical reaction?
No, it is not a chemical reaction. Solidifying of fat in a chip pan is a physical change that occurs when the fat cools down and changes from a liquid state to a solid state.
