heat energy (put your hands over the light source to feel the heat). The First Law of Thermodynamics states that energy cannot be created or destroyed; it only changes form.
Apr 30, 2017 · Heat is the net energy flux between two objects. Heat has nothing to do with any one-way flux. Temperature change requires heat – the net result of all incoming and outgoing fluxes. When you believe that one source of energy is less important that another, you are violating conservation of energy. All W/m2 are created equal.
A great deal of heat energy comes from the Sun's light hitting Earth. Other sources include geothermal energy, friction, and even living things. This unit helps students understand what heat energy is, how it is transferred, how it is measured, and how insulation can keep heat in or out.
At BrightSource Energy, respect for the environment informs our every thought and action, from the technology we develop to the stewardship we practice.
