WebThe energy reaching the surface of the Earth from within can be measured to get heat flux, q.. q = - k dT/dz . Units of heat flux = Wm-2 which is equivalent to Js-1 m-2, and k is the thermal conductivity (Wm-1 K-1). The average heat flow from the Earth gives a q of approximately 0.08Wm-2 (equivalent to 80mWm-2).. But the flow is very uneven. WebThe terms thermal energy and heat energy are often used interchangeably as they both involve power created by heat. However, thermal energy refers to the stored or total internal energy of a system ‘s temperature, while heat represents thermal energy transfer. Temperature is the average kinetic energy inside an object.
