Answer:
1) 1.808 *10^8 vacancies per cm^3
2) 101,64ºC
Explanation:
You can use the following equation relating the number of vacancies with the energy required to produce them and the temperature:
Where N is the number atoms per unit of volume, you can calculate this number with the density of copper:
And you can substitute all values in the equation:
Now you solve for temperature and and use n as 1000 times the value of before:
<span>Gravity is a very important force. Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It makes it possible to use human-made satellites and to go to and return from the Moon. It makes planets habitable by trapping gasses and liquids in an atmosphere. It can also cause life-destroying asteroids to crash into planets.</span>
Answer:
Molecules of matter such as liquid, gas and solid still move even if the energy is transferred because it isn't a hundred percent. There is still energy and the time it took to transfer that said energy would have changed its state of matter.
Explanation:
Solid -the molecules are tight together. (touching)
Liquid - the molecules are close but not touching about mid way(not to far not to close)
Gas- the molecules in gasses are far apart.
It almost always goes from solid to liquid to gas. but in extreme conditions it could be different.
