Question

How does a star form?

Answer 1

There are huge clouds of gas and dust in space.Due to some shock waves the gas get accumulated in one point and its mass increases.

Explanation:

This will cause more mass to be attracted due to gravity. after a long period the pressure and temperature at the core will be very high..When the temperature reaches about 15 million atn the core nuclear fusion will start and star began to shine..In the core 4 hydrogen atoms will fuse togather and form 1 helium atom and about 0.7% mass will be converted into energy.
