Question

1. choose the correct answer.

a pack of batteries has ____ potential energy stored inside of it.
chemical
gravitational
elastic

1. choose the correct answer.

most energy ends up as what type of energy?
heat
nuclear
light
chemical

Explanation:

• For the first question: Batteries store energy in the form of chemical potential energy. Gravitational potential energy is related to height and mass, and elastic potential energy is related to stretched or compressed objects.
• For the second question: According to the law of energy conservation and the concept of energy degradation, most energy eventually dissipates as heat. Nuclear energy is a specific form of energy from nuclear reactions, light is a form of electromagnetic energy, and chemical energy is stored in chemical bonds.

Answer:

1. chemical
2. heat
