Homework Statement
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.
Homework Equations
P/T= constant
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.
