Answer:
D) A car's air bag expands by igniting a chemical.
Step-by-step explanation:
Fireworks are a type of pyrotechnic display that are created by chemical reactions that release energy in the form of light, heat, and sound. These chemical reactions are usually accomplished through the use of oxidizers, fuel, and various chemicals that are carefully combined to produce the desired effects.
A) Muscles work to perform a task is not caused by a chemical reaction that releases energy. Instead, it is caused by the contraction of muscle fibers, which generate force to move the body or an object.
B) Fuel burns and heats the surroundings is caused by a chemical reaction that releases energy. When fuel, such as gasoline or wood, is burned, it reacts with oxygen in the air to release heat and light.
C) A battery supplies current to a device is not caused by a chemical reaction that releases energy. Instead, it is caused by the flow of electrons through a conductive material, such as a wire.
D) A car's air bag expands by igniting a chemical is caused by a chemical reaction that releases energy. The air bag is typically activated by a chemical reaction between two substances that generates a large amount of gas, which rapidly inflates the air bag to protect the occupants of the vehicle.
