Explanation:
Following are the kinetic theory of gases postulates:
1) Space-volume to molecules ratio is negligible.
2)There is no force of attraction between the molecules at normal temperature and pressure. The force of attraction between the molecules build when the temperature decreases and the pressure increases.
3) There is large space between the molecules resulting in continuous motion.
4) The free movement of molecules results in collision which is perfectly elastic.
5) The molecules have kinetic energy due to random movement. But the average kinetic energy of these molecules differs with temperature.
6) Molecules exert pressure on the walls of the container.
Answer:
The correct answer is - it provided water, food, transportation, and excellent, fertile soil for growing food.
Explanation:
People of Egypt moved to the northern Nile river due to various reasons. In this region, the soil is very excellent and helps in growing crops as the soil is fertile due to the appropriate climate and water resources.
It is aso helps in selling and transporting the products as it was a trade route at the time. As it is known Egypt has almost no rainfall so the only way crops can get water is through the Nile river.
<span>The another way of exciting the electrons without using a bunsen burner is by using microwave owen as it heats by exciting electrons directly without using a flame.There are several opportunities to excite electrons within an atom or a molecule.The energies to excite a single electron in an atom start at roughly 10-19J, which is approximately the energy of red light.</span>
"If you pass white light through a red filter, then red light comes out the other side. This is because the red filter only allows red light through. The other colors (wavelengths) of the spectrum are absorbed. Similarly, a green filter only allows green light through."
I'm not too sure it either wouldn't be too visible or it would have a darker color..lmk if you have questions
