Question 1

Described Nucelar Fusion

Answer 1

1. Hydrogen Nuclei Collide: Extreme temp and pressure in core force hydrogen (protons) together
2. Fusion occurs: 4 hydrogen combine to form helium nucleus in a process called proton -proton chain
3. Mass converts to energy: helium nucleus have slightly less mass than an organically hydrogen nuclei this “missing” mass becomes energy
4. Energy radiates outwards: released energy travels through sun layers reaching earth as sunlight (8 mins)

Question 2

What is the process when hydrogen combines to form helium

Answer 2

Proton-proton chain

Question 4

What formulas describes mass to energy conversion

Answer 4

E=mcsquared

Question 5

How do red stars form?

Answer 5

When stars exhaust their core hydrogen, fusion stops and gravity compresses the core. This heats the currounding hydrogen shell which begins fusing instead. Energy out put increases greatly causing layers to expand.

Question 6

What give a red star its colour

Answer 6

Cooler on the surface giving it a red colour

Question 7

What are white dwarfs

Answer 7

Are teh dense and how remnants of stars like our SUn after they have exhausted their nuclear fuel and shed their outer layers. Size of earth but have a mass of a sun
