What will happen after a nebula contracts and its temperature increases?

What will happen after a nebula contracts and its temperature increases?

As the nebula contracts, whatever initial tumbling/rotational motion is increased to conserve angular momentum (just like when a spinning figure skater brings in their arms). The nebula flattens into a disk. Gravitational contraction also causes the pressure to increase which causes the cloud to heat up.

What will most likely happen after a stellar nebula contracts and its temperature increases to 10 million Kelvin?

Which of the following are loops of matter flowing from the Sun? Which galaxies are sometime shaped like footballs? The most massive stars end their lives as which type of object? Which is a group of stars, gas, and dust held together by gravity?

What happens after the nebula contracts?

A nebula (gas cloud) slowly contracts under the mutual gravity of all of the atoms in the cloud. As the nebula contracts, whatever initial tumbling/rotational motion is increased to conserve angular momentum (just like when a spinning figure skater brings in their arms). The nebula flattens into a disk.

In which of the following choices are the objects ordered from smallest to largest?

Phillip E. From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.

What was the contraction of the nebula caused by?

Contraction of insterstellar cloud. Solar system formed about 4.6 billion year ago, when gravity pulled together low-density cloud of interstellar gas and dust (called a nebula)(movie).

Why do nebulae contract?

As a ball of dust and gas contracts under its own gravity, it begins to shrink and its core begins collapsing faster and faster. This causes the core to heat up and to rotate.

What happens during the stellar nebula stage?

Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar. Eventually the temperature reaches 15,000,000 degrees and nuclear fusion occurs in the cloud’s core.

What happens to the core temperature of a star as it ages evolves?

Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants. The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.

How do nebulae affect Earth?

Explanation: The closest nebula is the Orion Nebula at more than 1300 light years from Earth. It is so remote that nothing that happens there can influence the Earth. The only influence is to have beautiful colors and shapes and to let us dream one day to go there and explore them.

What force causes the nebula to begin to contract?

The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.

Is Nebula bigger than galaxy?

Simply put, the main difference between galaxies and nebulae are an extreme difference in size, as well as their basic structure. A nebula is a cloud of dust and gas, usually tens to hundreds of light years across. A galaxy is much larger — usually thousands to hundreds of thousands of light years across.

What is most likely to be found in a nebula?

Answer: Most nebulae are composed of about 90% hydrogen, 10% helium, and 0.1% heavy elements such as carbon, nitrogen, magnesium, potassium, calcium, iron.
