Firecrackers produce three types of energy: sound, light and intensity. That flourishing sound you hear after the blast is from the fast arrival of energy, which makes the air grow quicker than the speed of sound, causing a shockwave.
What else can I help you with?
Do Fireworks change blank into blank and blank energy?
Fireworks change chemical energy in the form of gunpowder into light, heat, and sound energy when ignited. The gunpowder in the fireworks undergoes a rapid chemical reaction, releasing energy in the form of a colorful display.
Why are fireworks considered a chemical change?
they are actually considered exothermic change because they release energy.
Is the explosiveness of fireworks a physical or chemical change?
The explosiveness of fireworks is a chemical change. It occurs when the chemical compounds in the fireworks undergo a rapid chemical reaction, resulting in the release of energy in the form of heat, light, and sound.
How do fireworks demonstrate the transformation of energy?
The energy transformation during fireworks show are, fireworks convert chemical energy into light and sound energy.
Is shooting off fireworks a physical change?
Yes, shooting off fireworks involves a physical change, as the fireworks explode and release energy in the form of light, heat, and noise. The chemical composition of the fireworks changes during the explosive process, but no new substances are created.
Is fireworks an example of exothermic change?
It's a exothermic reaction because heat and light is being released.
In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
Which form of energy is not producd when chemical energy stored in fireworks is transformation?
Nuclear energy is not produced when chemical energy stored in fireworks is transformed. The chemical reactions in fireworks release thermal (heat), light, and sound energy, but not nuclear energy.
How do fireworks demonstrate transformation of energy?
Fireworks demonstrate the transformation of energy. When there is a chemical reaction, it creates sound and light energy.
Is fireworks a physical or a chemical change?
Are fireworks a chemical change or a physical change? Fireworks are a chemical change because once you lite it, it reacts to the fire.eat dodo doodadsdodo doodads
Is potential energy used in fireworks?
Yes, potential energy is used in fireworks. When the fireworks are ignited, chemical potential energy is converted into thermal energy, which causes the fireworks to explode and create light and sound.
Are exploding fireworks an example of a physical or chemical change?
Exploding fireworks are an example of a chemical change. The chemical compounds within the fireworks undergo a chemical reaction when ignited, resulting in a new substance being formed that releases energy in the form of heat and light.
