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.
no it's more of a physical change because you are changing the physical state of the water from a liquid into a gas.
a chemical change would happen if you added acid to the water or disolved a salt in it, maybe...
No.
Physical change because the water molecules stay unchanged during boiling, also the germination phase helps this be proved correct=)
Correct, boiling water changes from liquid to gas.
Short answer: Pressure. Long answer: Pressure changes the boiling point of a substance. The higher the pressure, the higher the boiling point, and vice versa. For example, boiling water in the mountains is easier than boiling water at sea level. Note that boiling water is not necessarily hot. You can boil water at room temperature if the pressure is low enough (For example, using a vacuum generator)
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.
Melting of a solid to a liquid, or evaporation of a liquid to a gas. The physical state is changed but it is the same substance (though some substances do breakdown under heating, then it becomes chemical)
No.
Boiling water is physical change.
boiling water
No, That would be a physical change....A chemical change would be for like example: Water Evaporting, Water Boiling, Water Freezing...etc

cold water heating up to its boiling point a physical change or a chemical change
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.
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.
