Ground water has some minerals dissolved in it. if you heat this water, collect the vapor in another container, and then cool it, you will get pure, or distilled, water. what makes this process a physical change? it forms a new substance (minerals), which is a physical change. it forms a new substance (water vapor), which is a physical change. it changes the color of water, which is a physical change. it changes the molecular structure of water, which is a physical change. it separates dissolved substances, which is a physical change.

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point
