Which outcome relating to Helium-4 production occurs during stellar nucleosynthesis via the proton-proton chain?

💡 Explanation

Increased average binding energy results because greater stability of He-4 after nuclear fusion generates energy via mass defect, a form of mass-energy equivalence. This outcome increases energy; therefore it warms, rather than the limited effects achieved by other options.

• Which outcome occurs when increased pressure is applied isothermally during the transition within boiling liquid?
• Which risk increases when amorphous polymer filaments in fused deposition modeling become cooled past the glass transition by convection?
• Which consequence results when a fluid's viscosity assumption breaks down in a Navier-Stokes equation simulation?
• Which consequence results when antibonding orbitals become significantly populated?
• Which electrical characteristic results when dopants modify band gaps?
• Which property dominates near a black hole event horizon due in line of the equivalence principle?
