Question

which are products of nuclear fusion? check all that apply. energy helium gas high temperatures hydrogen gas low pressure

Explanation:

Nuclear fusion occurs when light nuclei (like hydrogen) combine under high temperature/pressure. The core reaction in stars fuses hydrogen into helium, releasing large amounts of energy. High temperatures and pressure are requirements for fusion, not products; hydrogen is a reactant, and low pressure is not related to fusion products.

Answer:

energy, helium gas
