Question

Suppose that the temperature at the center of the sun is 2.00107 K. What is the average translational kinetic energyof a proton in the Sun's interior?

A)4.96 108 J
B)2.48 108 J
C)2.23 104 J
D)4.14 10-16 J
E)2.76 10-16 J Hint: The temperature is a direct measure of the averagetranslational molecular kinetic energy. E(kin) = (1/2)m v^2 = (3/2)k(B)T.

Explanation / Answer

      E = (3/2)kBT       =(3/2)(1.38*10-23J/K)(2.0*107K)       = 4.14*10-16J
