Question

choose the ingredients needed for nuclear fusion. check all that apply. heavy nuclei helium gas high temperatures hydrogen gas low pressure

Explanation:

Step1: Recall nuclear - fusion concept

Nuclear fusion involves light - nuclei combining.

Step2: Analyze heavy nuclei

Heavy nuclei are for fission, not fusion.

Step3: Consider helium gas

Helium is a product of hydrogen - hydrogen fusion.

Step4: Evaluate high temperatures

High temps overcome repulsion of nuclei.

Step5: Examine hydrogen gas

Hydrogen is the main fuel for fusion.

Step6: Look at low pressure

Low pressure helps in the process of fusion by allowing nuclei to move more freely to combine.

Answer:

helium gas, high temperatures, hydrogen gas
