What is claimed is: 1. A composition comprising HFC-1234yf, HFC-32 and HFC-125; wherein said HFC-1234yf is present at about 20 weight percent to about 99 weight percent. 2. The composition of claim 1 , wherein said HFC-1234yf is present at about 20 weight percent to about 80 weight percent. 3. The composition of claim 1 , wherein said HFC-1234yf is present at about 20 weight percent to about 70 weight percent. 4. The composition of claim 1 , further comprising a lubricant selected from the group consisting of polyol esters, polyalkylene glycols, polyvinyl ethers, mineral oil, alkylbenzenes, synthetic paraffins, synthetic napthenes, and poly(alpha)olefins. 5. The composition of claim 1 , further comprising a stabilizer, water scavenger, or odor masking agent. 6. The composition of claim 1 , wherein said stabilizer is selected from the group consisting of nitromethane, hindered phenols, hydroxylamines, thiols, phosphites and lactones. 7. A method of producing cooling, said method comprising: evaporating said composition of claim 1 in the vicinity of a body to be cooled and thereafter condensing said composition. 8. A method of producing heat, said method comprising: condensing said composition of claim 1 in the vicinity of a body to be heated and thereafter evaporating said composition. 9. A method for replacing a high GWP refrigerant in a refrigeration, air-conditioning, or heat pump apparatus, wherein said high GWP refrigerant is R410A, said method comprising providing the composition of claim 1 to said refrigeration, air-conditioning, or heat pump apparatus that uses, used or is designed to use said high GWP refrigerant. 10. A method of using the composition of claim 1 as a heat transfer fluid composition, said process comprising transporting said composition from a heat source to a heat sink. 11. A refrigeration, air-conditioning, or heat pump apparatus containing a composition of claim 1 . 12. A method of forming a foam comprising: a. adding to a foamable composition the composition of claim 1 ; and b. reacting the foamable composition under conditions effective to form a foam. 13. A process for producing aerosol products comprising the step of adding a composition of claim 1 to active ingredients in an aerosol container, wherein said composition functions as a propellant. 14. A composition comprising from about 5 to about 70 weight percent HFC-1234yf, from about 5 to about 70 weight percent HFC-32, and from about 5 to about 70 weight percent HFC-125. 15. The composition of claim 14 , further comprising a lubricant selected from the group consisting of polyol esters, polyalkylene glycols, polyvinyl ethers, mineral oil, alkylbenzenes, synthetic paraffins, synthetic napthenes, and poly(alpha)olefins. 16. A method of producing cooling, said method comprising: evaporating said composition of claim 14 in the vicinity of a body to be cooled and thereafter condensing said composition. 17. A method of producing heat, said method comprising: condensing said composition of claim 14 in the vicinity of a body to be heated and thereafter evaporating said composition. 18. A refrigeration, air-conditioning, or heat pump apparatus containing a composition of claim 14 . 19. A composition comprising from about 10 to about 80 weight percent HFC-1234yf, from about 5 to about 80 weight percent HFC-32, and from about 10 to about 80 weight percent HFC-125. 20. The composition of claim 19 , further comprising a lubricant selected from the group consisting of polyol esters, polyalkylene glycols, polyvinyl ethers, mineral oil, alkylbenzenes, synthetic paraffins, synthetic napthenes, and poly(alpha)olefins. 21. A method of producing cooling, said method comprising: evaporating said composition of claim 19 in the vicinity of a body to be cooled and thereafter condensing said composition. 22. A method of producing heat, said method comprising: condensing said composition of claim 19 in the vicinity of a body to be heated and thereafter evaporating said composition. 23. A refrigeration, air-conditioning, or heat pump apparatus containing a composition of claim 19 .
