Why does the temperature climb in a birth of a star as more mass is drawn into the core?

1 Answer

When mass increases the pressure at center goes up.


This pressure compress the matter and creats heat and temperature,.Irregularities in the density of the gas causes a net gravitational force that pulls the gas molecules closer together. Some astronomers think that a gravitational or magnetic disturbance causes the nebula to collapse. As the gases collect, they lose potential energy, which results in an increase in temperature." quote from scientific american.
