Answers
Hope it will help you
Answer: Correct answer is (B)- Fusion. It is the process by which the sun produces energy and then releases it.
Step-by-step explanation:
The sun, being a huge hydrogen burning furnace produces lots of heat,light and radiation, and releases about 4 x 10^26 watts per second.
Process of fusion:
Hydrogen consists of one proton and one electron.
Low temperatures: positive charge repels each other---- no fusion.
High temperature and pressure( when sun condenses):
4H atoms fuse into a single helium atom. Some of the mass gets converted into energy.
-----It all begins at 8 million degrees K.
Then as it reaches higher temperatures there is fusion of heavier elements----3 atoms of helium undergo fusion to form a single carbon-12 atom at 100 million degrees K.
