Answer:
(a) Kav Ne = Kav Kr = 7.29x10⁻²¹J
(b) v(rms) Ne= 659.6m/s and v(rms) Kr= 323.7m/s
Explanation:
(a) According to the kinetic theory of gases the average kinetic energy of the gases can be calculated by:
(1)
<em>where
: is the kinetic energy, k: Boltzmann constant = 1.38x10⁻²³J/K, and T: is the temperature </em>
<u>From equation (1), we can calculate the</u><u> average kinetic energies for the krypton and the neon:</u>
(b) The rms speeds of the gases can be calculated by:
<em>where m: is the mass of the gases and
: is the root mean square speed of the gases</em>
For the neon:
For the krypton:
Have a nice day!
The potential energy is 490 because
1•9.8•50=490 hope it helps!
