3. The compressions makes the gasses very hot atoms lose electrons and become plasma of ionised atoms
and free electrons
4. NUCLEAR FUSION occurs where nuclei gain enough energy to travel at high enough speeds to overcome
electrostatic repulsion between the other (+ve) nuclei…

Gorgeous Gamma




Inside the sun
The sun mainly emits visible light.

Core - hottest region, where the nuclear fusion reactions
that power the Sun occur.

Radiative zone - energy is carried outward through this
layer as thermal radiation by photons.

Convective zone - heat…

1. Chromosphere absorbs EMR the atoms in the chromosphere are raised to a higher energy level = EXCITED
STATES
2. They then lose the extra energy by emitting photons of EMR
3. These emitted photons of EMR produces specific coloured lines/frequencies on the emission…

2. Electrical discharge is present
3. The molecules react under these conditions
4. Products formed are amino acids

Second Experiment
1. Dilute solution of ammonia and hydrogen cyanide (HCN) is made
2. Frozen for a few days
3. Identified amino acids + adenine (base)…
