Question

a magnetic field of 1.2 t is applied to paramagnetic gas. the atoms of gas have magnetic dipole moment

Answer 1

The question is INCOMPLETE. The full question is;

"a magnetic field of 1.2tesla is applied to a paramagnetic gas.the atoms of the gas have magnetic dipole moment of 1.5*10^-23 joule/tesla. at what temperature will the mean translational kinetic energy of an atom of the gas be equal to the energy required to change the alignment of atom's magnetic dipole from antiparallel to parallel(to magnetic field)? "

Answer:

At 17.5K the mean translational kinetic energy of an atom of the gas be equal to the energy required to change the alignment of atom's magnetic dipole from antiparallel to parallel(to magnetic field)

Answer 2

4MB=3*Boltzmann constant*T

4*1.5*10^-23*1.2 = 3*1.38*10^-23*T

T=1.74K
