Deuterium (2h), when heated to sufficiently high tempera- ture, undergoes a nuclear fusion reaction that results in the production of helium. the reaction proceeds rapidly at a temperature, t, at which the average kinetic energy of the deuterium atoms is 8 × 10216 j. (at this temperature, deu- terium molecules dissociate completely into deuterium atoms.)
(a) calculate t in kelvins (atomic mass of 2h 5 2.015).
(b) for the fusion reaction to occur with ordinary h atoms, the average energy of the atoms must be about 32 × 10216 j. by what factor does the average speed of the 1h atoms differ from that of the 2h atoms of part (a)?

Temperature=3.86*10^7K

V1=1.4

(a) Calculate T in kelvins (atomic mass of 2H 5 2.015).

(b) For the fusion reaction to occur with ordinary H atoms, the average energy of the atoms must be about 32 × 10216 J. By what factor does the average speed of the 1H atoms differ from that of the 2H atoms of part (a)?

k.E =3/2kT

K.E is the kinetic energy

k=boltzmann constant

T=Temperature in kelvin

juxtaposing the given values we have

T=2(KE)/3k

T=2*8*10^-16/(3*1.38*10^-23)

T=3.86*10^7K

Temperature=3.86*10^7K

b. average speed V=

R is the gas constant

T absolute temperature in kelvin

M molar mass

since R.T,PI are constant

we are comparing between hydrogen and helium particles

V=

V1/V2=

V1=V2

V1=V2* 1.4

V1=1.4

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
