According to the Ideal Gas Equation, PV=nRT.
Since n=Mm (mass / Molar mass) and density ρ=Vm, we can substitute to find the relationship between density and pressure:
P=VmMRT=ρMRT
Rearranging for the ratio of density to pressure:
Pρ=RTM
For a fixed mass of a specific gas, the Molar mass (M) is constant. Thus, the ratio is inversely proportional to the absolute temperature:
Pρ∝T1
- Initial Condition: T1=10∘C=10+273=283 K.
x=283k(where k is a constant)
- Final Condition: T2=110∘C=110+273=383 K.
x′=383k
- Calculate Ratio:
xx′=k/283k/383=383283
x′=383283x
