Heat Capacity Calculations Chemistry Tutorial AUSeTUTE
Specific heat capacity is the energy required to raise the temperature of 1 g of substance (Al) by 1°C. The specific heat capacity of aluminium is given as J°C 1 g 1 . The temperature change is not 1°C, it is 20°C, so we need to multiply the specific heat capacity by 20 in order to determine the amount of energy that would be required to raise the temperature of 1g of Al by 20°C:
Dietary Energy for Swine eXtension
Apr 26, 2010· Metabolized energy (ME) is the usable energy of a feed for the pig to live and grow and is obtained by subtracting the urinary energy loss from the DE. In most cases, metabolizable energy of complete swine diets is approximately 96% of the digestible energy content, so the conversion from DE to ME can be easily made.
