Chefs need to know physical and chemical properties in the kitchen, so they will know what will happen to different substances when they are heated, cooled, etc.
Also, they need to know so they are able to tell the difference between the properties. Physical properties can return to their natural state (water freezing to ice, then ice melting back to water). However, chemical properties cannot be changed back once they are changed (a raw egg is changed when cooked, but you cannot un-cook an egg)
Scientists can use chemical properties to identify certain substances or even separate it. One way to identify a substance is using universal indicator paper. Many scientists use flames instead.
The good cooking is only food chemistry.

These properties are specific for each substance.
Because after a chemical reaction new substances are obtained, with new properties.

The chemical properties of an object show what a chemical change did to that substance.

chemical properties can be observed only when the substances in a sample of matter are changing into different substances

SUBSTANCE
Chemical properties are properties that depend on the substances reactions with other substances. Physical properties can be observed without changing the composition of the matter.
