At room temperature (25 °C, 77 °F, or 298.15 K), one kilocalorie per mole is approximately equal to 1.688 kT per molecule. Even though it is not an SI unit, the kilocalorie per mole is still widely used in chemistry [ 1 ] and biology [ 2 ] for thermodynamical quantities such as thermodynamic free energy , heat of vaporization , heat of fusion ...

The hottest part of Brazil is the northeast, where temperatures of more than 38 °C (100 °F) are frequently recorded during the dry season between May and November. Along the Atlantic coast from Recife to Rio de Janeiro, average temperatures range from 23 to 27 °C (73 to 81 °F).
V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...
