Question

The minimum order temperature required for nuclear fusion

Answer 1

High temperature - The high temperature gives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons.

Fusion requires temperatures about 100 million Kelvin (approximately six times hotter than the sun's core).

At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about.

The sun achieves these temperatures by its large mass and the force of gravity compressing this mass in the core. We must use energy from microwaves, lasers and ion particles to achieve these temperatures.
