Answer:
10. When a firecracker explodes, stored chemical energy tums into sound and light energy.
The energy transformations in a firecracker are chemical energy to light, thermal, and sound energy. Firecrackers begin with stored energy as chemical energy inside the firecrackr
What other type of energy is also released during this transformation?
A. Thermal
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work (e.g. Lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed.
B) Nuclear
Nuclear power plants consist of nuclear reactors. These reactors use Uranium rods as fuel and heat is generated by the process of nuclear fission. Neutrons smash into the nucleus of the uranium atoms, which roughly split into half and release energy in the form of heat. Carbon dioxide gas is pumped through the reactor to take the heat away. The hot gas then heats water to form steam. This steam drives the turbines of generators to produce electricity. Thus, the steps of energy conversion are:
Nuclear energy → Thermal energy → Kinetic energy in steam → Kinetic energy in turbine
C. Electrical
What type of energy is released at each energy transformation?
The body releases thermal energy in the form of heat. Nerves use electrical energy to communicate within the body. Plants transform radiant energy into chemical energy. Electric eels transform chemical energy into electrical energy.
D. Mechanical
Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science to design, analyze, manufacture, and maintain mechanical systems.[1] It is one of the oldest and broadest of the engineering branches.
Solution:
When a firecracker explodes, the stored chemical energy turns into sound and light energy. Also, when the cracker is lighted using a matchstick or a lighter, the heat energy or the thermal energy produced will be converted into mechanical energy which allows the cracker to move or spin from one point to another or shoot up into the atmosphere.
