When the battery is connected to a circuit, chemical reactions occur, converting this stored chemical energy into electrical energy. This process generates a flow of electrons, providing power to devices. Different battery types use various chemical compositions to optimize performance and energy capacity.

Conventional social institutions are established structures and mechanisms within a society that govern behavior and facilitate social order. These include family, education, religion, economy, and government, each serving specific roles in maintaining societal norms and values. They shape individuals' interactions and influence social cohesion by providing frameworks for relationships and cultural practices. Overall, they play a crucial role in the functioning and stability of a society.

When you eat, the body converts the chemical energy stored in food into usable energy through the process of digestion and metabolism. Enzymes break down carbohydrates, fats, and proteins into smaller molecules, which are then absorbed into the bloodstream. These molecules are further metabolized to produce adenosine triphosphate (ATP), the primary energy currency of cells. This ATP fuels various bodily functions, including muscle contraction, brain activity, and maintaining homeostasis.

When a car stereo is turned on, electrical energy from the car's battery is transformed into sound energy. The stereo converts the electrical signals into sound waves through speakers, allowing the audio to be heard. Additionally, some energy is also dissipated as heat during this process.
