Question

is mixing air into egg whites a physical or chemical change? (1 point) both chemical physical neither

Explanation:

A physical change involves a change in the form or appearance of a substance without altering its chemical composition. Mixing air into egg whites only changes the texture and volume (due to the incorporation of air bubbles), but the chemical nature of the egg - white proteins remains the same. A chemical change would involve a reaction that changes the chemical structure of the substances involved, such as when bonds are broken or formed to create new substances. Since no new substances are formed when air is mixed into egg whites, it is not a chemical change. And it is clearly a physical change as there is a change in the physical state (volume, texture) of the egg - white mixture.

Answer:

physical
