A paramagnetic gas at room temperature $$27\ ^\circ\text{C}$$ is placed in an external uniform magnetic field of magnitude $$B=1.5\ \text{T}$$. The atoms of the gas have magnetic dipole moment $$\mu=1.0\mu_B$$ where $$\mu_B=\frac{eh}{4\pi m}$$ is Bohr magneton, and $$m$$ is the mass of electron. The energy difference $$\Delta U_B$$ between the parallel alignment and the antiparallel alignment of the atom's magnetic dipole moment with respect to the external field is $$x\times10^{-4}\ \text{eV}$$. The value of $$x$$ is
