Flashcards in 31.1 - How Stars Begin Deck (6)
What are the energy transfers as a cloud of gas becomes a star?
Gravitational potential energy -> Random kinetic energy -> Nuclear energy -> EM wave energy
What happens as the kinetic energy of the gas particles increases?
They collide more
What happens when the temperature and pressure within a star reach a critical point?
Nuclear fusion begins
What does this do?
Releases an outward force to stabilise the star against its own gravity
What nuclei are involved in the first steps of nuclear fusion within a star?
