What energy transformation best describes a firecracker exploding?
When a firecracker explodes, stored chemical energy turns into sound and light energy.
Which type of energy is stored in crackers?
Answer: The chemical energy stored in the cracker is converted into radiant energy (the light), acoustic energy (the sound) and thermal energy (the heat). A small amount is also converted into kinetic energy as the pieces of the cracker fly apart.
What energy transfer takes place in a burning match?
The matchstick contains a lot of stored chemical energy. When the matchstick is burning, the chemical energy is transformed to heat energy which is then transformed to light energy.
Which kind of energy is required to ignite when the cracker explodes?
Answer: The chemical energy stored in the cracker is converted into radiant energy (the light), acoustic energy (the sound) and thermal energy (the heat).
What kind of energy is an explosion?
kinetic energy
Explosions occur when energy is transformed from one kind e.g. chemical potential energy to another e.g. heat energy or kinetic energy extremely quickly. So, like in inelastic collisions, total kinetic energy is not conserved in explosions. But total momentum is always conserved.
When a firecracker explodes stored chemical energy turns into sound and radiant energy what other type of energy is also released during this transformation?
Answer: the chemical energy stored in a cracker is converted in radiant energy(the light),acoustic energy (the sound), and thermal energy (the heat). A small amount is also converted in to kinetic energy as the pieces of the firecracker fly apart.
When a firecracker explodes stored chemical energy turns into sound and light energy what other type of energy is also released during this transformation?
Some of the chemical energy stored in the fireworks is converted to kinetic energy to send the rocket skyward; some compresses the air rapidly, producing sound and still more energy is transformed into light of many colours.
