When a bread knife has reddish brown spots is it chemical or physical change?
The reddish-brown spots on a bread knife are typically a result of rust, which is a chemical change. Rust forms when iron in the knife reacts with oxygen and moisture in the air, leading to the formation of iron oxide. This process alters the chemical composition of the metal, distinguishing it from a physical change, which would not involve such a transformation.

Clear water can turn brown when boiled due to the presence of dissolved organic matter, such as tannins or humic acids, which are often found in natural sources like rivers or lakes. When heated, these substances can become more concentrated and release their color. Additionally, if the water contains minerals or sediments, boiling can cause these particles to clump together or oxidize, leading to a brownish hue. Lastly, any contamination from pipes or containers used for boiling can also contribute to discoloration.
