Heat and pressure
Chemical energy in the gunpowder is transformed into thermal, light, and sound energy when a firecracker explodes. The chemical energy is released as heat and light from the rapid combustion of the gunpowder, creating the explosion and producing sound waves.
When a firecracker explodes, chemical energy stored in the fireworks' gunpowder is rapidly converted into thermal (heat) and light energy. The gunpowder undergoes a rapid combustion reaction, releasing energy in the form of heat and light as the firecracker explodes.
When a firecracker explodes, in addition to sound and light energy, heat energy is also released. This is because the chemical reaction that occurs during the explosion generates heat, which is then given off as thermal energy.
The energy of a firecracker is stored in the form of gunpowder , a solid . The energy is released by ignition , where it is first transformed to heat energy , then to a gas , which causes the explosion , or release of energy.
The energy stored in firecrackers is primarily chemical potential energy. This energy is released rapidly when the firecracker explodes through a chemical reaction, producing heat, light, and a loud noise.
During a firecracker explosion, in addition to sound and light energy, thermal energy is also released due to the rapid chemical reactions that take place. This thermal energy contributes to the heat emitted during the explosion.
A firecracker uses chemical energy stored in the explosive material inside it. When ignited, this chemical energy is rapidly released as heat, light, sound, and pressure, causing the firecracker to explode.
Conversion of chemical energy into sound and light energy. Crackers burst with sound and generates light.
No. The explosion of a firecracker is a chemicalexplosion. Matter is converted from one form to another; molecules, that is, the atoms in the molecules, rearrange themselves releasing energy. That's the blast and the light. But the total mass of the substances involved is carried over into the combustion byproducts. No mass is lost. Chemistry does not change the involved mass in a reaction. Only nuclear reactions cause change in mass. In chemical reactions, energy can be released or absorbed according to the reaction and the constituent substances involved.
The energy released when dynamite explodes comes from the chemical reaction within the dynamite itself. The explosive compound in dynamite, such as nitroglycerin, rapidly decomposes and releases a large amount of heat, pressure, and gas, resulting in the explosion.
A stick of dynamite stores chemical potential energy, which is released in the form of heat and pressure when the dynamite explodes.
Burning a campfire is a transformation of chemical energy stored in the wood into heat and light energy, as well as some sound energy. The chemical energy is released through a combustion reaction as the wood undergoes oxidation with the oxygen in the air.
