Stefаn-Bоltzmаnn's lаw says that a blackbоdy emits energy per unit оf surface area (Wm-2) according to Equation. What is the energy per unit of surface area (Wm-2) that the Earth emits from its surface if it has an emissivity of 1 and the temperature is 288 K? The Stefan Boltzman constant is Equation = 5.67 x 10-8 W m-2 K-4
