Question

What is the energy of neutrons in thermal equilibrium?

Answer 1

Hello Mate

A thermal neutron is a free neutron with a kinetic energy of about 0.025 eV (about 4.0×10−21 J or 2.4 MJ/kg, hence a speed of 2.2 km/s), which is the most probable energy at a temperature of 290 K (17 °C or 62 °F), the mode of the Maxwell–Boltzmann distribution for this temperature.

Thanks

Answer 2

Answer:

At room temperature, Thermal neutrons have a kinetic energy of about 0.025 eV (electron volt) or about 4.0 × 10−21 J, or a speed of 2.2 km/s.
