How did the star Alnitak begin its life?
Each star in the solar system starts out in a nebula, a cloud of dust particles and gas.
Where the star came from?
Scientists believe that the Sun and our solar system formed at nearly the same time out of the solar nebula - an enriched interstellar gas and dust cloud that existed where our solar system now lives. The theorized order of events for the birth of our Sun is similar to what we see in newly forming stars today. Compression from nearby disturbances causes the interstellar medium to collapse. Small clumps of gas and dust break away from the larger cloud. These denser knots have gravity and begin to gather other gas and dust around them. Temperatures begin to rise due to the further increase in gravity from material in the collapsing gas cloud. The center of this fragmented gas cloud evolves quickly (over the next 100,000 years) to form a protostar and once pressure and temperatures reach a peak, nuclear fusion begins. for more info check related link
What is true of a gas as its temperature is decreased?
As the temperature of a gas decreases, its particles have less kinetic energy and move more slowly. This causes the gas to contract and its volume to decrease. Additionally, the pressure of the gas will also decrease with decreasing temperature.
What is the role of rotation in the process of stellar birth?
Rotation plays a key role in the process of stellar birth by influencing the collapse of a molecular cloud into a protostar. As the cloud collapses, conservation of angular momentum causes it to spin faster, forming a protostellar disk. This disk is where material accumulates to fuel the growth of the protostar.
Will an inert gas expand and contract with temperature?
It will contract.
What causes the gas and dust in a nebula to contract?
Gravity.
What causes nebula to begin to contract?
Nebulae begin to contract primarily due to gravitational forces. A disturbance, such as shock waves from nearby supernovae or collisions with other gas clouds, can trigger this contraction. As the gas and dust within the nebula clump together, gravitational attraction increases, leading to further collapse and the eventual formation of stars and planetary systems. Additionally, the cooling of the gas can enhance the process by allowing particles to come closer together.
What is matter from nebula that has begun to condense under the weight of gravity to begin formation of star?
The matter from a nebula that has begun to condense under gravity to form a star is called a protostar. As gravity causes the protostar to contract, the core temperatures rise until nuclear fusion ignites, and a star is born. This marks the transition from a cloud of gas and dust to a shining star.
What is a star called that begins as a large cloud of dust and gas?
A star that begins as a large cloud of dust and gas is called a protostar. It forms as gravity causes the dust and gas to clump together and initiate the process of nuclear fusion in its core.
How did the star Alnitak begin its life?
Each star in the solar system starts out in a nebula, a cloud of dust particles and gas.
How are stars formed, step by step, from the initial collapse of a cloud of gas and dust to the ignition of nuclear fusion in their cores?
Stars are formed through a series of steps starting with the gravitational collapse of a cloud of gas and dust. As the cloud collapses, it heats up and forms a protostar. The protostar continues to contract and heat up until the core reaches temperatures high enough for nuclear fusion to begin. Once nuclear fusion ignites in the core, the star is born and begins to shine brightly.
A fragment of a collapsing gas cloud that comes to equilibrium with a central temperature of 4 million k becomes what?
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.

What is a star birth?
A star birth refers to the formation of a new star from a collapsing cloud of gas and dust in space. As gravity causes the cloud to contract, the core temperature rises until nuclear fusion is ignited, marking the birth of a star. These new stars eventually stabilize and begin to generate energy through nuclear reactions in their cores.
What is interstellar gas cloud?
An interstellar cloud made of gas, dust, and plasma in a galaxy.
What is observed when ethylene gas is produced?
Ethylene gas causes produce to ripen. When ethylene gas is being produced you will notice the produce begin to ripen until it becomes overripe.
Is a cloud an example of a gas?
mustard gas
