What are the steps to prove that a burning of a candle is physical as well as a chemical change?
To prove that the burning of a candle is a physical and chemical change, you can observe the physical changes such as the melting of the wax and the formation of soot. Additionally, you can analyze the chemical changes by noting the production of carbon dioxide and water vapor during the combustion process. By observing both physical and chemical changes, you can demonstrate that burning a candle involves both types of transformations.
Is burning of coal a physical change?
Burning of coal is a chemical change, not a physical change. During the burning process, the chemical composition of coal changes as it reacts with oxygen to produce heat, light, and ash.
Is burning a match a physical change?
Yes, burning a match is considered a chemical change because it involves a chemical reaction that changes the composition of the matchstick and produces new substances like ash, carbon dioxide, and water vapor. This is different from physical changes, which do not alter the chemical composition of a substance.
How is a burning candle both physical and chemical changes?
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
What are some examples of chemical and physical changes grade 5?
Physical - Breaking of glass Boiling of water Melting of ice Cutting of vegetables Chemical - Burning of paper Cooking of food Rusting of iron Souring milk
How do geologists classify weathering changes?
they are neither physical nor chemical changes
Why is a burning candel a chemical change and not a physical changes?
Burning is a chemical reaction with oxygen (oxidation).
What are the physical changes of a plastic bottle?
Yes, burning (oxidation) is chemical change.

Burning of coal is a chemical change, not a physical change. During the burning process, the chemical composition of coal changes as it reacts with oxygen to produce heat, light, and ash.
Is a log burning a chemical or physical change?
Chemical change, because it is irreversible. The chemical composition of the substance actually changes. A physical change is a change of state, like water to ice. There, H20 is still H20.
Is burning a match a physical change?
Yes, burning a match is considered a chemical change because it involves a chemical reaction that changes the composition of the matchstick and produces new substances like ash, carbon dioxide, and water vapor. This is different from physical changes, which do not alter the chemical composition of a substance.
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
What is an example of a chemical change wood burning glass breaking water freezing?
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.
Is magnesium burning a physical change?
No, magnesium burning is a chemical change because the magnesium undergoes a chemical reaction with oxygen to form magnesium oxide. Physical changes do not alter the chemical composition of a substance, whereas chemical changes do.
Would the burning of a house be a physical change?
Mostly chemical, but physical changes also occur, such as when the windows blow out.
What are examples of chemical and physical change?
melting any metal is physical. rusting iron is chemical
