Heat capacity of benzene gas
Web1 de dic. de 2024 · Gas chromatography was used to analyze the initial and final concentrations of the benzene solution. The adsorption capacity of benzene (mg/g) by MWCNTs was estimated by: (1) q = C 0 - C m × V where C and C 0 are final and initial concentrations (mg/L) of benzene in water, V refers to the solution volume (L), and m … WebHowever, if heated it becomes a gas, and when cooled it becomes a solid. The phase diagram for toluene shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the toluene boiling point with changes in pressure.
