The fusion of hydrogen nuclei with the release of energy car be initiated by a fission reaction because the fission reaction
provides a
1. high temperature and high pressure
2. high temperature and low pressure
3. good supply of hydrogen nuclei
4. good supply of neutrons

bcde is the incorrect answer it is a

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
