which of the following is an example of only a physical change? (1 point) dry ice becoming vapor the creation of table salt the green color of the statue of liberty the smell of rotten eggs
Answer
Brief Explanations:
A physical change is a change in the form or state of matter without a change in its chemical composition. Dry ice (solid carbon - dioxide) becoming vapor is a phase change (sublimation) from solid to gas without altering the chemical identity of carbon - dioxide. The creation of table salt is a chemical reaction. The green color of the Statue of Liberty is due to a chemical reaction (oxidation). The smell of rotten eggs is due to the presence of hydrogen sulfide which is formed through chemical processes.
Answer:
dry ice becoming vapor
