The two changes, burning food on a stove and an engine using gasoline to power a car, share the following commonalities:
1. **Both are caused by heating** - Both processes involve the application of heat: burning food requires heat to ignite and cook, while an engine uses heat generated by the combustion of gasoline to power the car.
2. **Both conserve mass** - According to the law of conservation of mass, matter is not created or destroyed in a chemical reaction. In both cases, the mass of the reactants (food and gasoline) is conserved as they undergo chemical changes.
The statements regarding "both are only physical changes" and "both are caused by cooling" do not apply in this context. Both are chemical changes, and they are not caused by cooling.
