Question

what is chemical energy? the energy associated with the motion of sample of matter. the energy associated with the flow of electrical charge. a form of potential energy associated with the positions of the particles that compose the chemical system. the energy associated with the random motions of atoms and molecules in matter. part b list some examples of common substances that contain chemical energy. check all that apply. fruit falling from the tree. the burning of natural gas. a heated swimming pool. the burning of gasoline. a cup of hot tea.

Explanation:

Chemical energy is a form of potential energy related to the positions of particles in a chemical system. The burning of natural gas and gasoline involve chemical reactions that release stored chemical energy. Fruit falling from a tree is an example of gravitational - potential energy being converted to kinetic energy, a heated swimming pool and a cup of hot tea are related to thermal energy.

Answer:

Part A: A form of potential energy associated with the positions of the particles that compose the chemical system.
Part B:

• The burning of natural gas.
• The burning of gasoline.
