This shouldn't be a physical change as, the gold isn't being turned from it's liquid form to it's solid form. When we filter the water for gold flakes, we are essentially taking small amounts of gold from the water and collecting them together to form a larger and more apparent amount. No state change (ie, liquid to gas. Gas to liquid. Liquid to solid.) is taking place during the process.
No, this process of removing gold flakes by filtering them out is a physical change, not a chemical change. This is because the gold flakes are still the same substance before and after filtering; only their physical state has been altered.
filtering coffee is a physical change as no new products are formed after filtering and is reversible..
This is an example of physical separation technique called filtration. Filtration is used to separate solid particles from a liquid by passing the mixture through a barrier that retains the solid particles while allowing the liquid to pass through. In this case, the small gold flakes are retained by the filter while the water solution passes through, resulting in the separation of the gold flakes from the solution.
Filtering air to remove dust and pollen is a physical change because the process does not alter the chemical composition of the dust and pollen particles. It simply separates them from the air through physical means, such as using a filter.

Because the salt solution is monophasic; filtering is applied when a precipitate exist.

Physical
A solution does not have a chemical change, but it does have a physical change in state.
Dissolving is a physical change.
It is a physical change.
A solution is a material not a change; dissolving is a physical process.
No, filtering something is not a chemical change.
Filtering air to remove dust and pollen is a physical change. This is because the process does not alter the chemical composition of the air or the dust/pollen particles. Instead, it simply separates the particles based on their physical properties.
