Chemistry is really a normal thing to do with two plus two
This is due to the tightly packed crystal lattice of the metallic structure. The larger the amounts of delocalized electrons, the stronger the metallic bonds are.
Fructose is d sweetest sugar of all
Answer : The correct answer is A. Nuclear reactors using Pu-239
B. burning coal
The sources which are not renewable are known as "non- renewable sources of energy .
Non - renewable sources are those which get expired after rapid use and can never be reproduced . These sources replenishes in very long time . Examples : Coal , petrol or fuels etc .
1) Nuclear reactors using Pu-239 : Nuclear reactors uses radioactive elements like uranium , plutonium etc , which are present in limit . after frequent use of these elements , they will vanish off , Hence we can say nuclear reactors are Non renewable source of energy .
2) Burning coal : Coal is used as one of the major source of fuel . On rapid utilization of coal they will finished from earth . It takes thousand of year for formation of coal . Hence , it is a Non -renewable source .
3) Photo-voltaic cell: These are cells which used solar energy . Solar energy is obtained from sun . Hence solar energy is renewable source of energy so is the photo voltaic cell .
4) Geothermal energy : Geothermal energy is source of energy that is extracted from earth's thermal energy . Since thermal energy of earth is present in very large amount and can be reproduced , hence it renewable source of energy .
5)Wind energy : Wind energy is source of energy that is obtained from wind. And wind is renewable source so the wine energy too .
Consequently , we can say only two of them " Nuclear reactors and burning of coal " are Non renewable force of energy .
Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with <u>more and more </u>energy over time until vaporization occurred.
<h3>What is vaporization?</h3>
- Vaporization is the changing of a liquid into a gas.
- This is known as a phase change.
- This happens when the atoms receive enough heat energy.
- The heat energy provides the atoms with kinetic energy and causes them to move faster over time.
- When the kinetic energy is enough to rupture the bonds that hold a liquid together, it becomes a gas.
Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.
