Web2 mrt. 2024 · The boiling point of butane is close to 0 degrees Celsius, whereas the higher boiling point of butanone (79.6 degrees Celsius) can be explained by the shape of the … WebWe can calculate the boiling point with heat of vaporization by Clausius- clapeyron equation given by, ln(P2/P1)=−ΔHvapR⋅(1/T2−1/T1) Where, P1 – the vapor pressure of the substance at T1 P2 – the vapor pressure of that substance at T2 ΔHvap – the enthalpy of vaporization. R – the gas constant – generally expressed as 8.314 J/K⋅mol. Summary
