Question

the most probable velocity of neutron at 20 degree celsius is nearby​

Answer 1

Answer:

2200 m/s

Explanation:

The most probable velocity at 20°C is of particular importance since reference data, such as nuclear cross sections, are tabulated for a neutron velocity of 2200 meters per second.

Answer 2

Answer: The most probable velocity of a neutron is 2197 m/s.

Explanation:

To calculate the most probable velocity of a particle, we use the equation:

$v_o=\sqrt{\frac{2kT}{m}}$

where,

$v_o$ = most probable velocity of neutron

k = Boltzmann constant = $1.38\times 10^{-23}J/K$

T = temperature = $20^oC=[273+20]K=293K$

m = mass of neutron = $1.675\times 10^{-27}kg$

Putting values in above equation, we get:

$v_o=\sqrt{\frac{2\times (1.38\times 10^{-23}kg.m^2/s^2.K)_\times 293K}{1.675\times 10^{-27}kg}}\\\\v_o=2197m/s$

Hence, the most probable velocity of a neutron is 2197 m/s.
