∙ 11y agoIn order for a clump of matter in a gas cloud to become a star, it must be a whopping BIG gas cloud, so that the mutual gravitation of the cloud would cause it to collapse in on itself.
There are some theories that a large and diffuse gas cloud would be unlikely to spontaneously collapse under its own gravity without some substantial shock to the gas cloud. The shock wave of a nearby supernova explosion would not only provide the shock, but also contribute a substantial amount of newly-created heavy elements to the system. Such a supernova five billion years ago probably provided a lot of the iron, gold and uranium to our solar system, and also caused our stellar nebula to collapse, forming our Sun and our planetary system.

∙ 11y agoUndergo gravitational collapse, where the cloud of gas and dust collapses under its own gravity, causing high temperatures and pressure at its core. This leads to nuclear fusion reactions starting, creating a balance between inward gravitational force and outward pressure from fusion energy, resulting in a stable star.
The electron cloud becomes larger as the value of n increases because electrons in higher energy levels are on average farther from the nucleus. These higher energy levels have more sublevels and orbitals, resulting in a larger spatial distribution of the electron cloud. This increased distance from the nucleus leads to a larger orbital size.

um ok
I am not sure
it has to go through melting and solidification in order to become an igneous rock.
A star is formed out of cloud of cool, dense molecular gas. In order for it to become a star, the cloud needs to collapse and increase in density.
A fragment of a collapsing gas cloud that comes to equilibrium with a central temperature of 4 million K becomes a protostar. As gravity causes the gas to contract and heat up, nuclear fusion reactions ignite in its core, marking the birth of a star. The protostar will continue to evolve as it balances the inward pull of gravity with the outward pressure from nuclear fusion.
The states of matter are solid, liquid and gas. A solid melts to become liquid and a liquid evaporates to become gas. Sublimation is the direct change from solid to gas.
The major benefit of cloud services such as Microsoft Azure or AWS (Amazon Web Services) are that they enable companies to avoid upfront infrastructure costs. But also using a cloud can become a major expense. In the last couple of years there are tools that optimise cloud deployment, such as Cloudyn's, in order to downsize cloud costs. If you're interested in a free trial of such a tool have a look at: http://www.cloudyn.com/pricing/
Clouds need to reach a level of saturation where water droplets coalesce and become heavy enough to fall as rain. This typically requires a high enough concentration of water droplets in the cloud to overcome updraft forces keeping them aloft. The specific density of the cloud needed to produce rain can vary depending on factors such as the cloud's height, temperature, and atmospheric conditions.
The cloud must stay warmer than the surrounding air in order to keep growing.
No, Order does not matter
No. Multiplication is commutative so the order of the multiplicands does not matter. Multiplication is associative so the order in which the operations are carried out does not matter.
Hailstones are formed when updrafts in thunderstorms carry water droplets into freezing upper atmospheric levels, causing the droplets to freeze into ice pellets. As the hailstones fall through the storm clouds, they can accumulate more layers of ice as they are repeatedly carried back up by the updrafts. The hailstones eventually fall to the ground when they become too heavy for the updrafts to support.
The electron cloud becomes larger as the value of n increases because electrons in higher energy levels are on average farther from the nucleus. These higher energy levels have more sublevels and orbitals, resulting in a larger spatial distribution of the electron cloud. This increased distance from the nucleus leads to a larger orbital size.
No; it does not matter.
