A 14 g sample of neon gas has 1200 J of thermal energy. Estimate the average speed of a neon atom.

The average speed of a neon atom is 414.04 m/s

Explanation:

Given;

energy of the neon gas, E = 1200 J

mass of the neon gas, m  = 14 g = 0.014 kg

The speed of the neon atom is given by Maxwell-Boltzmann;

E = ¹/₂mv²

where;

v is the average speed of the neon atom

1200 = ¹/₂(0.014)v²

2 x 1200 = 0.014v²

2400 = 0.014v²

v² = 2400 / 0.014

v² = 171428.57

v = √ 171428.57

v = 414.04 m/s

Therefore, the average speed of a neon atom is 414.04 m/s
