Guys I'm weak in heat and kinetic theory, so I'm going to need extra guide and pointers from you guys to solve this and the coming questions. Thank you.
A constant-volume gas thermometer of volume 0.001m3 contains 0.05mol of a gas and is used to deduce values of temperature on the assumption that the ideal gas law is obeyed. In fact, one mole of the gas satisfies the relation [tex](p + \frac{a}{V_m^2})(V_m -b) = RT[/tex],
where a correct for intermolecular forces and b corrects for the effective size of the gas molecules.
(i) What form of the equation should be used for x moles of gas? Explain your answer.
(ii) Given that the thermometer was calibrated at the triple point of water, use the data below to calculat the error when the thermometer is used to measure a temperature near to that of boiling water: a = 0.08 Pa m6 mol -2; b = 3E-5 m3 mol-1.
Attempt:
I honestly don't know. Pointers anyone?
