Does nuclear power plant convert chemical energy into electrical energy?
What happens in a nuclear power plant is not a chemical reaction, but a physical reaction
The participants in chemical reactions are extranuclear electrons, and those in nuclear power plants are nuclei
So it's the conversion of atomic energy into electricity
Does nuclear power plant convert chemical energy into electrical energy?
It's about turning nuclear energy into electricity
Nuclear power plants, right? Atomic energy is converted into electricity
The nuclear power plant converts the nuclear energy inside the atom into the internal energy of water vapor, then the internal energy of water vapor is converted into the mechanical energy of steam turbine, and finally the steam turbine drives the generator to convert the mechanical energy into electrical energy!
It can be said that to is not a direct conversion, but first converted into heat energy, in the use of heat energy into kinetic energy. Finally, it is converted into electric energy
The energy in nuclear power plant has been transformed several times and its characteristics are analyzed
In a nuclear power plant, nuclear energy is first converted into (), () energy is then converted into (), and finally, () is converted into ()
Characteristics of nuclear power plant
In nuclear power plants, nuclear energy is first converted into internal energy, then into kinetic energy, and finally into electric energy
Characteristics of nuclear power plant: (clean) (low consumption) (low cost) (reliable operation)
Mechanical energy is converted into thermal energy.
The characteristics are not very clear. It's probably that the power generation is high, the demand for raw materials is small, and there are few geographical restrictions, but the law of energy utilization is low. I'm sorry to know that
Factors affecting resistance______ 、______ 、______ .
The factors that affect the resistance are material, length, cross-sectional area and temperature
A brief introduction to Edison
My English is not good: Edison is a great inventor, he is known as the king of invention, he invented 1000 kinds of things in his life
The answer is: the invention of the great
The rated voltage of a motor is 220 V, and the rated power is 5.5 kW. Its resistance is 0.4 ohm, so it can be calculated
(1) How many joules of heat are generated in one second?
(2) How many joules of electrical energy are converted into mechanical energy in one second
1) The heat generated in 1s is: q = w = I ^ 2rt = (P / U) ^ 2rt = (5.5kW / 220V) ^ 2 * 0.4ohm * 1s
=(250) joules
(2) How many joules of electrical energy are converted into mechanical energy in one second
Wtotal = Pt = 5.5kW * 1s = 5500j
E=5500J-250J=5250J
It's hard. You can calculate it according to the heat calculation formula
It's very simple
I won't help you with your homework
Calculation of copper wire resistance
The resistance value of 0.03 ohm per millimeter length of 0.03 square millimeter copper wire is known
Find out the resistance value of 0.05 square millimeter copper wire per millimeter length
What is the resistance value per millimeter length of 0.04 square millimeter copper wire?
R=pl/s
For the same substance, P is certain, but the topic tells L is certain, so the resistance value of 0.05 square millimeter copper wire per millimeter length is 0.018 ohm
Influence of conductor material on resistance
The resistance of a conductor is directly proportional to the length of the conductor and inversely proportional to the cross-sectional area of the conductor, and is related to the material of the conductor. The material mainly affects the resistance coefficient of the conductor
The resistance coefficient of conductor material is related to the resistance
