Question

For stars to form, the temperature of the hydrogen in a nebula must be more than 14 million Kelvin. How did gravitational attraction help achieve these high temperatures?

Answer 1

Answer:

the short version is density

Explanation:

so the outer part of the nebula is cold and dark 10-20k but at this temutre the gas clumps together heating it up more mass = more gravity = more heat and the gravity will pull more mass that will give the proto star the spherical shape we all know and love

Answer 2

Answer:

Gravitational attraction caused the volume of the nebula to decrease, which raised the particle motion and temperature at the center of the nebula to the necessary 14 million Kelvin.
