Best answer: What is the process of condensation in the solar nebula?

Composition of the Solar Nebula. As the protoplanetary disk cools, materials in the disk condensate into planetesimals. The solar nebular contains 98% Hydrogen and Helium (produced in the Big Bang), and 2% everything else (heavy elements, fusion products inside the stars).

What is condensation of a nebula?

In planetary science, the condensation sequence refers to the order in which chemical compounds transition from gas to solid phase in a protoplanetary nebula (disk), based on the condensation temperature of each compound.

What is condensation solar system?

The condensation theory of the solar system explains why the planets are arranged in a circular, flat orbit around the sun, why they all orbit in the same direction around the sun, and why some planets are made up primarily of rock with relatively thin atmospheres.

What is condensation in astronomy?

Condensation is the process of forming solid particles from the solar nebula, whereas the solar nebula is a cloud of interstellar gas and dust that condensed to form the entire solar system, including the sun and planets.

What is the process of nebular?

According to the nebular theory, stars form in massive and dense clouds of molecular hydrogen—giant molecular clouds (GMC). These clouds are gravitationally unstable, and matter coalesces within them to smaller denser clumps, which then rotate, collapse, and form stars.

What is condensation accretion?

Condensation is the construction of larger particles one atom ( or molecule ) at a time, whereas accretion is the sticking together of larger particles. … The planets swept up gas, debris, and small particles . … Clumps of matter form around the condensation nucleus.

What is condensation temperature?

The condensation temperature is that at which a given gas-phase constituent condenses into a liquid. This temperature depends on the physical and chemical state of the system.

What are the first four phases to condense out of the solar nebula?

As the early jovian planets captured large amounts of gas, the same process that formed the solar nebula — contraction, spinning, flattening and heating — formed similar but smaller disks of material around these planets.

What is the importance of the frost line in the solar nebula theory?

The lower temperature in the nebula beyond the frost line makes many more solid grains available for accretion into planetesimals and eventually planets. The frost line therefore separates terrestrial planets from giant planets in the Solar System.

Why did the nebula spin faster as they shrink or collapse?

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.

How the condensation theory explains the observed features of the present day solar system?

Describe the basic features of the condensation theory of the formation of the solar system. … After the solar nebula formed, cooled dust grains formed condensation nuclei around which matter began to accumulate. As they grew larger collisions and accumulation increased until fragmentation occurred and planets formed.

What happens gravitational condensation?

An object increases in size due to the addition of materials. What happens in the process of gravitational condensation? As the water is heated it changes forms from liquid to gas. Once you pull the lever, a plug gets opened automatically; this plug allows enough water to flow and fill up the basin.

What role did condensation temperatures play in the formation of the planets?

The condensation temperature of a substance is the temperature at which the substance solidifies from gas. In the inner part of the solar system where the temperature was high, only substances with high-condensation temperatures could become planets.

Is the solar system in a nebula?

Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.

What happens to a nebula when it spins faster Why?

Under the influence of its own gravity, the nebula contracts. As it contracts, it spins faster and faster, much like an ice skater who pulls in her arms. … As a result of the spinning, the nebula flattens out to form a disk, much like a clump of dough which is spun into a pizza.
