Which best describes stellar equilibrium
Key Points. There are two conditions that must be met for an object to be in equilibrium. The first condition is that the net force on the object must be zero for the object to be in equilibrium. If net force is zero, then net force along any direction is zero. The second condition necessary to achieve equilibrium involves avoiding accelerated ...Stellar nucleosynthesis is the process involving nuclear reactions through which fresh atomic nuclei are synthesized from pre-existing nuclei or nucleons.

Vega, Deneb, and Altair. Each of the following lists a constellation and a bright star.Hydrostatic Equilibrium. For the majority of the life of a star, the gravitational force (due to the mass of the star) and the gas pressure (due to energy generation in the core of the star) balance, and the star is said to be in ‘ hydrostatic equilibrium ’. This balance is finely-tuned and self-regulating: if the rate of energy generation ...The mass of a star determines exactly where it falls on the main sequence. As Figure 21.12 shows, massive stars on the main sequence have high temperatures and high luminosities. Low-mass stars have low temperatures and low luminosities. Objects of extremely low mass never achieve high-enough central temperatures to ignite nuclear reactions.Abstract.

Only of the major key determining the relative warmth regarding a climate is the slant of that …Terms in this set (18) Stars release huge amounts of radiation from their surfaces while on the main sequence. Why is this necessary if a star is to maintain hydrostatic equilibrium? - Fusion in the core generates huge amounts of energy which must be radiated away. - If the energy were not radiated away, the balance would be upset and the star ... interior. This is indeed what we defined as thermal equilibrium in Sec. 2.3.2. 5.2 Energy transport by radiation and conduction We have seen that most stars are in a long-lived state of thermal equilibrium, inwhich energy gen-eration in the stellar centre exactly balances the radiative loss from the surface. What would happenthe star is in hydrostatic equilibrium. If the time derivative in equation (1.11d) vanishes then the star is in thermal equilibrium. Notice, that we always assume that throughout the star the matter and radiation are in local thermodynamic equilibrium, LTE, no matter if the star as a whole is in hydrostatic or in thermal equilibrium.Small, relatively cold, low-mass red dwarfs fuse hydrogen slowly and will remain on the main sequence for hundreds of billions of years or longer, whereas massive, hot supergiants will leave the main sequence after just a few million years. A mid-sized star like the Sun will remain on the main sequence for about 10 billion years.
In chemistry, the equilibrium of a reaction is the point at which the products and reactants have the lowest free energy. The dynamic equilibrium, on the other hand, is the point at which products are being generated as fast as they are falling apart. This may not be the same as the chemical equilibrium, as enzymes force many reactions far past ...Star - Fusion, Mass, Energy: To interpret a stellar spectrum quantitatively, knowledge of the variation in temperature and density with depth in the star’s atmosphere is needed. Some general theoretical principles are outlined here. The gradient of temperature in a star’s atmosphere depends on the method of energy transport to the surface.

Dec 2, 2016 · 1. Gravity pulls gas and dust towards the core. 2. Inside the core, temperature increases as gas atom collisions increase. 3. Density of the core increases as more and more atoms try to share the same space. 4. Gas pressure increases as atomic collisions and density [atoms & space] increase. 5. Now we figured out that the equilibrium lies to the right, so therefore the equilibrium lies to the side that has the acid with the higher pKa value. So the equilibrium favors the weaker acid. So that's the short way of figuring out the position of equilibrium using pKa values. Here's another organic acid based mechanism that we've seen before.Which best describes stellar equilibrium? A.
