Is water a physical or chemical change?
Water is not a change of any sort. It is a substance. It can undergo physical and chemical changes.
Is coffee added to water an example of chemical change?
When coffee is added to water, that is a physical change. The coffee does not undergo a chemical reaction, the various chemical constituents of coffee remain the same. What changes is that the coffee is dissolved in water. If the water were to evaporate, leaving the coffee behind, it would be the same as it was (not counting the loss of some volatile constituents which would also evaporate, along with the water) before it was added to water.
Is water to vapor a physical change?
Yes, as the water does not undergo an inherent change in its chemical makeup.
Is filtering sand from water a chemical reaction?
No, it is a physical reaction because it doesn't undergo any change in chemical properties.
What is substance that undergo both chemical and physical changes?
A substance that is undergoing a chemical change is called a precipitate.------------------------------------------Initial substances in a chemical reaction are called reactants.
When you boil an egg does the water the egg or the pan undergo a chemical change?
Egg goes from liquid to solid. Water becomes steam, pan becomes hot. Cooking = chemical change.
When salt water has evaporated did it undergo a physical or chemical change?
When salt water has evaporated, it has undergone a physical change since the salt and water both retain their chemical configuration, only have changed their form.
Is brewing a coffee chemical or physical change?
physical. the water being added simply soaks through the coffee, so there's no chemical change.
What makes ice a chemical change?

What chemical changes does water undergo?
Electrolysis will turn water into hydrogen and oxygen gas.
When water is added to white copper and copper sulphate why is it a chemical change?
