Effect of protein overfeeding on energy expenditure ...
05/03/2015 · Background: Energy expenditure (EE) increases with overfeeding, but it is unclear how rapidly this is related to changes in body composition, increased body weight, or diet. Objective: The objective was to quantify the effects of excess energy from fat or protein on energy expenditure of men and women living in a metabolic chamber. ...
Extraction of Aluminium (examples, answers, activities ...
Aluminium oxide has a very high melting point over 2000 degrees celsius. So instead of trying to melt it, the aluminium oxide is dissolved in molten cryolite. Cryolite is an aluminium compound with a much lower melting point than aluminium oxide, and so using this reduces some of the costs in extracting aluminium.
Aluminium production environmental impact
• The amount of energy needed to make aluminium is 211 GJ per tonne, compared with GJ per tonne for steel. 3 • The extent of the energy use owes to the strength of the chemical bond between aluminium and oxygen is significantly stronger than the same bond between iron and oxygen. As a result, much more energy is required to split the ...

Energy Efficiency and Recycling: Start with Recycling ...
Extracting metals from ore is a much more energyintensive process than recycling. In fact, recycling scrap steel uses 75 percent less energy to process than iron ore, while recycling aluminum uses 95 percent less energy. It's been estimated, in fact, that by recycling a single aluminum soda can, enough energy gets saved to power a 60watt ...
