         3 . The aerosol of  claim 1  having a Global Warming Potential (GWP) of not greater than about 1000. 
     
     
         4 . The aerosol of  claim 1  wherein said at least one fluoroalkene is a compound of Formula II: 
       
         
           
           
               
               
           
         
         where each R is independently Cl, F, Br, I or H 
         R′ is (CR 2 ) n Y, 
         Y is CRF 2    
         and n is 0 or 1. 
       
     
     
         5 . The aerosol of  claim 4  wherein Y is CF 3 . 
     
     
         6 . The aerosol of  claim 5  wherein at least one R on the unsaturated terminal carbon is H. 
     
     
         7 . The aerosol of  claim 6  wherein n is 0. 
     
     
         8 . The aerosol of  claim 4  wherein n is 0. 
     
     
         9 . The aerosol of  claim 3  wherein Y is CF 3  and n is 0. 
     
     
         10 . The aerosol of  claim 1  wherein said at least one fluoroalkene comprises at least one tetrafluoropropene (HFO-1234). 
     
     
         11 . The aerosol of  claim 10  wherein said at least one tetrafluoropropene is HFO-1234ze. 
     
     
         12 . The aerosol of  claim 1  consisting essentially of one or more compounds in accordance with Formula (I). 
     
     
         13 . A sprayable composition comprising the aerosol of  claim 1 . 
     
     
         14 . The sprayable composition of  claim 13  further comprising material to be sprayed. 
     
     
         15 . The sprayable composition of  claim 14  wherein said material to be sprayed comprises at least one cosmetic material. 
     
     
         16 . The sprayable composition of  claim 15  wherein said at least one cosmetic material is selected from the group consisting of deodorants, perfumes, hair sprays, cleaning solvents, lubricants and combinations of these. 
     
     
         17 . The sprayable composition of  claim 15  wherein said material to be sprayed comprises at least one medicinal material. 
     
     
         18 . The sprayable composition of  claim 17  wherein said at least one medicinal material comprises a biologically active substance. 
     
     
         19 . The sprayable composition of  claim 17  wherein said at least one medicinal material comprises a drug. 
     
     
         20 . The sprayable composition of  claim 17  wherein said at least one medicinal material comprises a therapeutic agent.
