Explanation:

Ice melting involves a change from a solid to a liquid and the substances maintain the properties of water because the molecules never change.

Water boiling is a physical change as water molecules vibrate faster, they enter the gas phase and become water vapor.

Rubbing alcohol left uncovered will evaporate quickly into the air. ...

Boiling Liquids. Boiling uses heat to change a liquid to a gas. This occurs …

Clouding and Condensation. Clouding occurs when a substance …

Answer:

how to Identify a Physical Change

One way to identify a physical change is that such a change may be reversible, especially a phase change. For example, if you freeze water into an ice cube, you can melt it into the water again.

Is the change reversible? Not all physical changes are easy to reverse.

Was there a color change (with exceptions), bubble formation, or formation of a precipitate? These are all signs of a chemical change, not a physical change.

Is the chemical identity of the end product the same as it was before the change? If the answer is yes, it's a physical change. If the answer is no, it's a chemical change.

Examples of Physical Changes

Remember, the appearance of matter changes in a physical change, but its chemical identity remains the same.

Crushing a can

Melting an ice cube

Boiling water

Mixing sand and water

Breaking a glass

Dissolving sugar and water

Shredding paper

Chopping wood

Mixing red and green marbles

Sublimation of dry ice

Crumpling a paper bag

Melting solid sulfur into liquid sulfur. This is an interesting example since the state change does cause a color change, even though the chemical composition is the same before and after the change. Several nonmetals, such as oxygen and radon, change color as they change phase.

Chopping an apple

Mixing salt and sand

Filling a candy bowl with different candies

Vaporizing liquid nitrogen

Mixing flour, salt, and sugar

Mixing water and oil
