Homework Statement
water vapor is heated from 403.15k to 463.15k and is kept at a constant volume of 3m^2 its initial pressure is 10^5pa what is the density change?
Homework Equations
PV = nRT, D = M/V
The Attempt at a Solution
I don't really know where to go with this i found the final pressure with [tex]P_2 = \frac{P_1.T_2}{T_1}[/tex] but I am not sure this helped i also tried with P(M/D) = nRT but as you don't know M its not very helpful. I also though about using [tex]\delta{M} = \frac{\delta{E}}{c^2}[/tex] but couldn't find E without the mass...
