How does thermal energy flow
WebIn thermodynamics, heat is energy transferred to or from a thermodynamic system by mechanisms other than thermodynamic work or transfer of matter, such as conduction, … WebRegardless of the mechanism, heat flows from warmer to cooler areas until there is no longer a temperature difference. In your home, this means that in winter, heat flows directly from all heated living spaces to adjacent unheated attics, garages, basements, and especially to the outdoors.

Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ...
WebPrimary producers (usually plants and other photosynthesizers) are the gateway for energy to enter food webs. Productivity is the rate at which energy is added to the bodies of a group of organisms (such as primary producers) in the form of biomass. Gross productivity is the overall rate of energy capture. Net productivity is lower, adjusted ...
