C. Airplane and human body.

Explanation:

Chemical energy is a type of energy that is stored in the bonds of chemical compounds, such as atoms and molecules. The release of energy (a chemical reaction) transforms the substance into a completely new one. This is what happens with food after we eat it. Mechanical energy, on the other hand, is the sum of kinetic and potential energy in an object that is used to do a particular work.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
