Study the scenario. a firework is ignited, and explodes with a flash and a loud bang as it is blown apart. the system consists of: the firework, the earth, and the air. which choice best describes how energy is transformed in the system? when the firework is ignited, a chemical reaction absorbs energy from the surrounding environment. the energy is in several forms including sound and light, and mechanical energy of the fragments of the firecracker that are launched through the air. eventually all the energy released is transformed into thermal energy. when the firework is ignited, a chemical reaction releases energy in several forms, including sound, light, and the mechanical energy of the fragments being launched through the air. eventually all the energy released is transformed into mechanical energy. when the firework is ignited, a chemical reaction releases energy in several forms, including sound, light, and the mechanical energy of the fragments being launched through the air. eventually all the energy released is transformed into thermal or mechanical energy. when the firework is ignited, a chemical reaction absorbs energy from the surrounding environment. the energy is taken in in several forms including sound and light, and mechanical energy of the fragments being launched through the air. eventually all the energy is transformed into thermal energy.
