Which outcome occurs when high exhaust velocity is needed within a spacecraft thruster's limited expansion volume?

💡 Explanation

Higher velocities mean more kinetic energy must be imparted; therefore the increased vibrational energy equates to a dramatic hike in temperature via the mass-energy equivalence, because this dominates over just expansion rather than kinetic energy increases that would otherwise dominate efficiencies.
