A constant volume gas thermometer of volume V contains n amount of moles of gas. Assume the gas obeys the ideal gas law pv=nRt. The behavior is better described by:

[tex] \left(p+a\frac{n^2}{V^2}\right)\left(\frac{V}{n}-b\right)=RT [/tex]

a=0.1, b=3e^-5. The thermometer is calibrated at the triple point of water. How much will the temp measure in error at 100 C?

2. Relevant equations

Above

3. The attempt at a solution

I must be misinterpreting something. Do they mean error of the former with respect with the later?

Do I plug in temp for Vander, find pressure, plug that in for ideal gas law and find the temp?

The error being the difference between 100C-T(ideal)?
