How good a device is at transferring energy input to useful energy output is called efficiency. Both useful energy transferred and total energy supplied are measured in joules J. The energy supplied to a LED bulb is J. Out of this total energy supplied, J is usefully transferred. How efficient is the light bulb? The LED bulb is quite efficient since most of the energy supplied is transferred usefully. Most of the energy dissipated goes to raising the temperature of the surroundings. How is vsepr used to classify molecules?
What are the units used for the ideal gas law? How does Charle's law relate to breathing? What is the ideal gas law constant? How do you calculate the ideal gas law constant? How do you find density in the ideal gas law? Does ideal gas law apply to liquids?
Written in collaboration with Tore Hulgaard. This applies to everything from natural gas boilers, biogas engines and wood chip fired power plants to waste-to-energy plants. The definition is therefore based on the assumption that the condensation heat from water vapour in the flue gas is lost. This actually corresponds precisely to what will be done at large scale at Amager Bakke. Mixed, moist waste with an energy content LHV of
