cessation of all life (metabolic) processes. Death may involve the organism as a whole (somatic death) or may be confined to cells and tissues within the organism. Causes of death in human beings include injury, acute or chronic disease, and neoplasia (cancer).
R409A is a blend of HCFC refrigerants introduced to retrofit R12 in air conditioning and refrigeration applications.CFCâs are commonly accepted as having an overall detrimental effect on the environment through both their ozone depletion potential and global warming potential and consequently are being phased out completely.
The existing atmosphere surrounding the earth contains a little less than one percent of the inert gas Argon, an approximate total of 6.59 x 1019 grams. The isotope Argon-40 (40AR) is 99.6 percent of the total Argon. The only know source of 40Ar is the radioactive decay of Potassium-40 (40K), of which 11.2 percent decays into 40AR and the remainder into Calcium-40 (40CA).
