Question

(11%) Problem 6: Nuclear fusion-the energy source of the Sun, hydrogen bombs, and fusion reactors-occurs much more readily when the average kinetic energy of the nuclei is high Suppose you want the nuclei in your fusion experiment to have average kinetic energies of 5.5 x 10-14 J. What temperature, in kelvins, is needed for that?

Explanation / Answer

KE = (3/2)(R/NA) T

KE = 5.5 x 10^-14

R = 8.314

NA = 6.022 x 10^23

putting these values,

T = 2.66 x 10^9 K
