Which cell is the energy output of a star?

The energy output of a star comes from its core, where nuclear fusion reactions take place. During fusion, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process.


Do Hotter stars age more slowly then cooler stars?

The surface temperature is not a reliable indicator about how long a star will last. However, the total energy output is. If a star produces a lot of energy, it will burn through its fuel faster.


How are energy and mass related in a star?

The same as everywhere else. Every mass has associated energy. Every energy has associated mass. Possibly this question is about the energy output of stars. Usually, the more mass a star has the higher its rate of energy output.


What is a measure of the total energy radiated by the star in one second called?

A star's luminosity is the measure of the total energy radiated by the star in one second.


What is a supernova and what happens?

A supernova is the catastrophic death of a star, characterized by a massive output of energy.


How is energy generated in a star cores?

Energy in a star's core is generated through nuclear fusion, where hydrogen atoms combine to form helium releasing a massive amount of energy in the process. The extreme temperature and pressure in the core of a star make this fusion process possible, sustaining the star's energy output.


Why the temperature of the stars vary from one another?

The temperature in the core of a star depends, to a great extent, on:* The star's mass. The general tendency is that high-mass stars are hotter. * Where the star is in its life cycle. The star's core temperature will vary over time. On the other hand, the star's surface temperature also depends on its size. Thus, it is possible that PRECISELY because a star is hotter in the core, it gets bigger, and the surface temperature DECREASES (though its total energy output increases).


Is an orange star hotter then a yellow star?

The temperature of a yellow star's photo sphere is hotter than that of and orange star. However the total energy output of an orange star may be greater than that of a yellow star.


What are 2 characteristics that affect the temperature of a planet?

Two characteristics that affect the temperature of a planet are its distance from the sun and its atmosphere composition. The amount of sunlight a planet receives is determined by its distance from the sun, affecting its temperature. The composition of a planet's atmosphere can trap heat, leading to higher temperatures, or allow heat to escape, resulting in lower temperatures.


If a red star and a white star radiate energy at the same rate can they be the same size If not which must be the largest Why?

They cannot be the same size. The red star must be larger. Red stars are cooler that blue stars and so radiate less energy for a given amount of surface area. In order to radiate the same amount of energy as a blue star, the red star must therefore have a larger surface area.


The luminosity of a star is related to its .?

At a higher temperature, the star will shine more brightly for each square meter of surface. The total luminosity per square meter is approximately proportional to the fourth power of its absolute temperature. This refers to the energy output, considering all types of electromagnetic waves, not just visible light.
