heat.

Short answer: Rocket engines produce intense heat by burning propellants such as liquid hydrogen and liquid oxygen.

The Reel says liquid-fueled engines like the Space Shuttle's produce exhaust above 3,000 degrees Celsius, hot enough to melt steel, and release energy at up to 10 gigawatts; I left the power figure attributed to the Reel. Launch pads use flame trenches to divert exhaust and water deluge systems to absorb heat and sound. The footage, credited to astronomy4u, shows a rocket launch.

Video transcript: heat.: Rocket Exhaust Can Top 3,000 Degrees Celsius

Did you know? Rocket take-offs produce intense heat from chemical combustion in their engines. Liquid-fueled rockets like the Space Shuttle generate exhaust temperatures exceeding 3,000 degrees Celsius, hot enough to melt steel. The heat results from burning propellants, such as liquid hydrogen and oxygen, releasing energy at rates up to 10 gigawatts. This extreme thermal output requires flame trenches and water deluge systems to absorb and dissipate heat. NOW YOU KNOW!
