1. The problem statement, all variables and given/known data An Aerosol has a of pressure 250kpa at 17 C.The aerosol is left in the sun and its temp.rises to 27 C.Calculate new pressure in the can if its a 35% increase in the amount of vapour present. 2. Relevant equations P/T= constant 3. The attempt at a solution well tbh i am just confused.. do i get T= into kelvin, ok i tried that too... my first attemp was: 1)(273.15+27)-(17+273.15)=10kelvin so what i did:10x250x10^3/100= 25kPa so pressure at 27 is: 250+25=275Kpa 2) 2nd attempt: PV=nRT P/T=nr/v =>P/T= constant 250x10^3/10kelvin=25kpa... which if i add to 250 gives me same answer.. lol i have confused my self badly -(. first i forgot to convert C into Kelvin . Thanks for the replies in adv.
