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.
Given an electrical circuit or device Be able to compute instantaneous rate of energy use (power). Be able to compute how much energy is used over a period of time. Be able to compute how much energy is stored in an electrical storage device like a battery or a capacitor.iven an electrical circuit or device Be able to compute instantaneous rate of energy use (power).
