Is shortening melting a chemical change or chemical property?
Shortening melting is a physical change, not a chemical change or chemical property. When shortening melts, it undergoes a change in state from solid to liquid without any change in its chemical composition.
Is spilling water a chemical change?
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
Is Cleaning a painted surface with acid a chemical or physical change?

Is flettening a chemical change?
No, flattening is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas flattening simply changes the shape or appearance of the object.
What are the corresponding evidences shown that a chemical change occurred?
chemical change occurred when new chemical substance was created
When a kettle is boiled you can tell it is not chemical change?
There are 4 evidences of a chemical reaction : -Change of colour. -Formation of precipitate. -Release of energy. -Effervescence.
What are the most common evidences of chemical reactions?
Some signs (or evidence) of chemical change are: a gas is produced, the temperature changes, a substance disappears, a solid is formed a colour change occurs, a new odour is produced.
What are the evidences a chemical change has taken place?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence -formation of new compounds
What are the evidences of chemical change and which is the most important?
Some indicators of a chemical reaction are:- formation of new compounds- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence

What are some evidences that a chemical change occur?
Some evidence that a chemical change has occurred include the formation of a precipitate, a change in color or odor, the production of gas bubbles, or a change in temperature. These observable changes indicate that a new substance has been formed with different chemical properties from the original substances.
What are the evidences that the earth is revolving around the sun?
we experience climate change, our seasons change and scientists have proven it.
What are some evidences of a chemical change?
Cooling and warming the solutions are physical change. When your hand or your body after washing gets dry it's a ohysical change. When you stir your coffee or your tea it's a physical change. But when you cook your food or when the petrol of cars burn it's a chemical change. Because the compositions of the molecules changes. The most complex chemical change happens in our body everyday.And the enzymes are involved there. The photosynthesis of plants are another examples of chemical changes. When you wash your hand by detergents, they acts by fats and pollutions then your wash will be cleaned and it's another example of chemical changes.
