Question
Which of the following is not a physical change?Dissolution of common salt in waterDissolution of oxygen in waterDissolution of carbon dioxide in waterDissolution of sugar in waterc and d
Solution
All of the options you provided (Dissolution of common salt in water, Dissolution of oxygen in water, Dissolution of carbon dioxide in water, Dissolution of sugar in water) are examples of physical changes.
A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. The size or shape of matter may be changed, but no chemical reaction occurs.
In all the given options, the substances (salt, oxygen, carbon dioxide, sugar) are simply dissolving in water, they are not chemically reacting with the water to form a new substance. Therefore, none of the options is an example of a non-physical change.
