No, a chemical change is when a substance and forms one or more new substances, it changes its composition.
examples:
changes in color
production of gas
formation of precipitate
Boiling water is an example of physical change, it can be any phase change.
Boiling water is a physical change because it doesn't change the chemical composition of the water molecules. The water molecules simply gain enough energy to break away from their liquid state and become a gas, without any new substances being formed.
Yes, boiling water to make steam is a physical change. This is because the water undergoes a change in state from liquid to gas without any change in its chemical composition.
A rubber band undergoes a physical change when it is stretched and pulled.
it goes from water (a liquid) to water vapor (a gas)! the 3 main physical states are solid, liquid and gas, so when it goes from one to another, this is defined as a physical change. you're welcome.
Erosion includes a physical change to rocks.Her physical change was so dramatic her friends hardly recognized her.Dieting causes a physical change to body appearance.
No.
Boiling water is physical change.
No, That would be a physical change....A chemical change would be for like example: Water Evaporting, Water Boiling, Water Freezing...etc

Burning wood is an example of a chemical change. The wood undergoes a chemical reaction with oxygen in the air to produce new substances such as carbon dioxide, ash, and water vapor.
Boiling water is a physical change because it does not change the chemical composition of the water.
No.
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
It depends on what is boiling. If you are boiling WATER, then it is NOT a chemical change, it is a physical change (change of state from liquid to gas). If you are cooking food on the stove, a chemical change is occuring. That is, the chemical bonds within the food molecules are actually changing. One way you can tell that it is a chemical change is that you can't "uncook" food, but you can condense steam back into water.
yes
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
