No, passing tap water through a filter is a physical change, not a chemical change. The filter simply removes impurities and particles from the water, without altering its chemical composition.
physical. the water being added simply soaks through the coffee, so there's no chemical change.
No, only through chemical reactions. Physical changes never change the chemical makeup of something. For example, water tuning in to ice is a physical change. Ice and water both have the chemical symbol H20. On the other hand, a sodium - water reaction forms Sodium Hydroxide and Hydrogen. The compound, hydroxide, is formed.
That is a physical change.
No, this is definitely a physical change, absolutely not a chemical.
I think making coffee is a chemical change because the signs for a chemical change are: there is a gas given off, a colour change,a different smell,heat given out or absorbed and the change cannot be easily reversed. In this case colour change and and a different smell are underlined and also you cannot regain the same ingredients you started with to make the coffee.
No, This is a process to obtain a solid from an aqueous solution. No chemical process is taking place during filtration.

The chemical reaction of water with sodium is a chemical change.
That is a physical change.
It is not a chemical change.
Calcium reacting with water is a chemical change.
This is a physical change. The bubbles are pockets of steam which is the same chemical as water, just in a different state.
Boiling water is a physical change because it does not change the chemical composition of the water.
No, because the chemical properties of the water do not change.
