ETFL 60 = Elevated Temperature Flame Limit @ 60 Â°C. HOC = Heat Of Combustion. Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes R- or Refrigerant.. Thus, CFC-12 may also be written as R-12 or Refrigerant 12.An alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon-to-carbon double bond.hemical refrigerants are assigned an R number which is determined systematically according to molecular structure.
The energy stored in a capacitor is almost entirely in the electric field produced between the plates. It takes energy from a battery or some other power source to move electrons to one of the plates and away from the other. This makes one plate positively charged and the other negatively charged.
Energy Stored. Energy cannot be created or destroyed, but it can be saved in various forms. One way to store it is in the form of chemical energy in a battery. When connected in a circuit, energy stored in the battery is released to produce electricity.nergy Stored. Energy cannot be created or destroyed, but it can be saved in various forms.
