Need answers for the blue parts,thank you!!
Which statement is correct about the boiling? select the correct answer. O a. a dynamic equilibrium exists between the liquid and vapor phase. O b. the molecular bonds in the liquid are broken rapidly. O c. the vapor pressure of the liquid equals the external pressure above the liquid surface. O d. the vapor pressure of the liquid equals the pressure exerted by its vapor phase. O e. the vapor pressure of the liquid is less than the external pressure above the liquid surface.
