Abstract: This paper uses some fundamental concepts of physics, takes into account the uncertainties at quantum scale, applies the laws of thermodynamics and kinetic theory of gases and arrives at an inequality which provides a relation between time, extent and energy of a system.

Keywords: Heisenberg’s Uncertainty Principle, Average Kinetic Energy, 1st Law of Thermodynamics, Total Internal Energy, Specific Heat, Universal Gas Constant, Avogadro’s Number, Uncertainty in Position, Absolute Zero, Planck’s Temperature, Dimensional Analysis
