	abstract = {<div>We investigate the chemical potential μ and specific heat <em>CV</em> of a two-dimensional electron gas at temperatures <em>T</em>\&lt;1 K subject to high magnetic fields <em>B</em> that correspond to filling factors <em>ν</em>\&lt;1. We found out that at <em>ν</em>=1/2, the chemical potential is pinned at ℏω_c/2 which is equal to the energy of the first Landau level. The μ(<em>T</em>) increases when <em>ν</em>\&gt;1/2 and decreases when <em>ν</em>\&lt;1/2. This behavior is dictated by the change in the number of states available to the electrons. We also found out that μ(<em>B</em>) converged at ℏω_c/2 and this trend has a negligible <em>T</em>-dependence. When this behavior of the chemical potential was used in calculating the specific heat at the fractional quantum Hall filling factors, <em>CV</em>(<em>T</em>) exhibited a humpy behavior as compared to its smoothly increasing trend at the integral quantum Hall regime. This trend is a direct consequence of the discontinuities in the chemical potential.</div>},
