Stellar equilibrium is also known by its other term hydrostatic equilibrium. A star is considered to be in equilibrium when the pressures located in the star balance out the force of gravity. The pressure is thermal pressure that results from the mixture reactions that is happening in the star's core.

The balance between pressure caused by heat and gravity caused by the star's mass the Milky Way arms extend from a core full of black holes elliptical galaxy contains mostly older stars with a red color irregular galaxy contains dust, gas and young starsThis is because solids have a fixed volume, and density is defined as mass per unit volume. Since neither mass nor volume change with temperature for solids, the density remains constant. Therefore, the density of lead at 90°C remains as 11.3 x 10³ kg/m³, the same as at 0°C. The concept that a solid's density doesn't change with temperature ...

Stellar Life Cycle. Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the age of the universe.

of hydrostatic equilibrium. While the star is burning hydrogen in its core, the temperature is highest at the center. For an ideal gas, this temperature gradient helps support the star, while for an isothermal core, the density gradient alone must support the stellar mass, and the density gradient steepens.Study with Quizlet and memorize flashcards containing terms like Which best describes the difference between osmosis and diffusion?
