What is The Approx Volume of Hydrogen That Is Fusing In Our Sun Per Sec?

Answer 1

The Sun is about halfway through its main-sequence evolution, during which nuclear fusion reactions in its core fuse hydrogen into helium.

Each second, more than 4 million tonnes of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation; at this rate, the Sun will have so far converted around 100 Earth-masses of matter into energy. The Sun will spend a total of approximately 10 billion years as a main sequence star.

Answer 2

Cat barf is correct... this is not a straight forward answer... but...gererally....

The sun fuses Hydrogen at the rate of 6x10^11 kilograms/sec.

Volume is a meaningless unit of measure here...
What is the gas pressure you would like to have the answer calculated for?

One mole of an ideal gas at STP occupies 22.4 liters.

The Molar mass of Hydrogen plasma is certainly 1g/mole.

so...6x10 ^11 = 600000000000 kg = 600000000000000g = 600000000000000 moles x 22.4 = 134400000000000000 Liters of Hydrogen gas. That is about 33,600,000,000,000,000 Gallons of Hydrogen gas. Thirty Three thousand Trillion Gallons per second.

I hope I've been helpful.

Answer 3

This is hard to gage. First, you have to know the energy generated by fusion. Second, the form of hydrogen in the sun is much different than our typical concept of a gas. It is a very dense plasma being held under terrific pressure, high gravity and temperature.

Answer 4

I once read, that 320 billion tons of hydrogen are fusing into 270 billion tons of helium per second. The so called "mass defect" (2x2H > 1x4He, difference of 50 billion tons of mass) is because of the partial conversion of mass into energy, i. e. light, other radiation and heat (E=mc²).

Answer 5

the weight is 2 million tons per second.

Answer 6

i think appromaxitly 1 million per second
