What temperature does helium fusion require?
100 million K
Stellar Fusion Requirements
| Fusion | Fusion By-product | Minimum Core Temperature |
|---|---|---|
| Hydrogen | He | 13 million K |
| Helium | C, O | 100 million K |
| Carbon | O, Ne, Mg, Na | 500 million K |
| Neon | O, Mg | 1.2 billion K |
What temperature does helium fuse to carbon in Kelvin?
100,000,000 Kelvin
Once the central temperature reaches T > 100,000,000 Kelvin, helium can fuse into carbon – a new energy source.
What temperature does helium fuse to carbon quizlet?
the heavier the element, the higher the temperature to fuse it. C) helium to carbon fusion takes at least 100 million K to start.
What temperature does carbon fuse at?
At 200,000,000 degrees Celsius, the helium atoms fuse to form carbon atoms in the core. The last of the hydrogen gas in the outer shell is blown away to form a ring around the core.
Why does helium fusion require higher temperatures?
Helium fusion requires higher temperatures than hydrogen fusion because greater electrical charge leads to greater repulsion (100 million K, compared to 15 million K).
What temperature is fusion?
100 million degrees
On Earth, to produce net power, fusion reactions must take place at very high temperatures of at least 100 million degrees, which is some seven times hotter than the centre of the Sun. At these very high temperatures the fusion fuel turns into a plasma.
How does helium fuse into carbon?
When the temperature in the core reaches about 100 million degrees, the helium will begin to fuse into carbon by a reaction known as the triple-alpha process, because it converts three helium nuclei into one carbon atom. This generates a great deal of heat. In short, the center of the helium core explodes.
What happens when helium fuses into carbon?
Helium burns into carbon, and carbon combines with helium to make oxygen. The core of the star becomes rich in carbon and oxygen nuclei, and the star’s surface temperature goes up to become a horizontal branch star.
What is the critical temperature at which hydrogen can fuse into helium in the star’s core?
From the release of gravitational energy as the protostar continues to shrink. What is the critical temperature at which hydrogen can fuse into helium in the star’s core? 100 million K.
What is the minimum temperature when two hydrogen atoms fuse helium?
about 100 million Kelvin
In order to fuse two hydrogen atoms two things are required: high temperature and high pressure. The minimum temperature required to fuse hydrogen is about 100 million Kelvin, which is about six times the temperature in the core of our Sun.
