Answer 35

Helium

Question 36

What happened when star uses up hyrdoegen

Answer 36

Helium core collapses and thin hyrdrogen layer expands. It becomes red giant.

Question 37

Why are stars red giant

Answer 37

Red because cooled and giant because expanded.

Question 38

What would happen to redo giants if the star was size of our sun

Answer 38

Helium fuse to form carbon and outer hydrogen is released. Become white dwarf.

Question 39

What will happen to 10x our. Sun

Answer 39

Star will form heavy elements like iron which will not fuse. The star will then go supernova. While atoms in outer layer fuse.

Question 40

If mass is 1.4-3x our sun

Answer 40

It will go supernova and then become a neutron star.

Question 41

If star is more than 3x our sun

Answer 41

The star collapses on itself and becomes black hole

Question 42

How do black holes work

Answer 42

Take up no space but 100x more massive than sun. Swallows everything near and galaxies orbit them.
