4. Nuclear Fusion in Stars
• Stars such as the sun are basically
hot balls of hydrogen and helium gas
that emit light.
• They are held together by the
enormous gravitational forces caused
by their own mass.
• Inside the core of a star, these forces
create a harsh environment, with
pressure more than a billion times the
atmospheric pressure on Earth.

5. Nuclear Fusion in Stars
• Inside the core of a star, these forces
create a harsh environment, with
pressure more than a billion times the
atmospheric pressure on Earth.
• The temperature is hotter than 15
million kelvins, and the density is
over 150 times greater than that of
water.

6. Nuclear Fusion in Stars
• The temperature is hotter than 15
million kelvins, and the density is
over 150 times greater than that of
water.
• In extreme conditions, nuclear fusion
reactions combine the nuclei of
hydrogen atoms into helium with a
release of energy.
• This energy flows outward,
balancing the inward pull of gravity.
