Boiling water in a kettle is a physical change. This is because the change is reversible, and it involves a phase transition from liquid to gas without changing the chemical makeup of water molecules.
by exessive use of juices and cold drinks.
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
It is a chemical change which manifests a physical effect of gas being evolved from a liquid. If the gases already existed and were just coming out of solution, it would be a physical change, but since it is a change from water molecules to oxygen and hydrogen molecules it is definitely a chemical change, not a physical one.
IT can cause global warming or it can cause horrible storms like hurricans and tornados but chemical change affects air whitch causes polution and other disters will and can accure most offen thunder stroms witch puts electricity into the air
Yes, temperature have generally an important effect.
no its a chemical change (i just did i project on making ice cream in meh class and one question was "is this a chemical or physical change? how do u know?"
No, the process of ice melting at 0 degrees Celsius is a physical change, not a chemical property. It involves a phase change from a solid to a liquid state without any change in the chemical composition of the ice.

Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.
i think physical and chemical because for physical u r mixing it with the water. And for chemical I think it is because mixing drink mix with water is goes the effect the outcome chemical produced with both so it can also become a chemical change.....................
