Expert Solution

Step 1

A chemical change is defined as the change in the chemical formula of the compounds. So whenever there is change in the formula of the compound that will be called as chemical change.

Similarly a physical change is defined as a change where chemical formula remains same just the physical condition of compound changes. Like evaporation where only the phase of compound is changing from liquid to gas keeping the chemical formula as it is.
