There now exists significant evidence that the overdense, 1-2 MK active regions loops observed at EUV wavelengths are cooling. One heating model for these loops is that they are impulsively heated and then cool with no additional energy input. At some point in the loop's evolution before it reaches 1-2 MK, the density and temperature at the apex of the loop will resemble the expected density and temperature for a steady, uniformly heated loop; we term this the loop's equilibrium time. In our previous work, we have determined that the equilibrium conditions of a loop are related to the total amount of energy released in the loop. In this poster, we investigate the relationship between the cooling time measured at 1.5 MK and the equilibrium density and temperature in hopes to relate the observed cooling time with the total energy released in the loop. To do this, we calculate a grid of solutions to the one-dimensional hydrodynamic equations and develop an empirical relationship between the cooling time and equilibrium density and temperature. We then discuss the ability to further relate these values to the total energy released in the loop.
