(a)
Interpretation:
What is the freezing point of the given liquid must be explained?
Concept Introduction:
Freezing point of a liquid is the temperature at which the vapor pressure of the liquid is equal to the vapor pressure of solid.
(b)
Interpretation:
What is the boiling point of the liquid must be explained?
Concept Introduction:
Boiling point is the temperature at which a liquid starts boiling to vapor and until all the liquid is not boiled off temperature remains same. The vapor pressure of the liquid is equal to atmospheric pressure.
(c)
Interpretation:
Which out of heat of fusion or heat of vaporization is greater must be explained?
Concept Introduction:
Both heat of fusion and heat of vaporization is done at constant temperature with the help of latent heat.

Introductory Chemistry: A Foundation
- Define critical temperature and critical pressure. In terms of the kinetic molecular theory, why is it impossible for a substance to exist as a liquid above its critical temperature?arrow_forwardThe following data are the equilibrium vapor pressure of limonene, C10H16, at various temperatures. (Limonene is used as a scent in commercial products.) (a) Plot these data as ln P versus 1/T so that you have a graph resembling the one in Figure 11.13. (b) At what temperature does the liquid have an equilibrium vapor pressure of 250 mm Hg? At what temperature is it 650 mm Hg? (c) What is the normal boiling point of limonene? (d) Calculate the molar enthalpy of vaporization for limonene using the Clausius-Clapeyron equation.arrow_forwardWhat are intermolecular forces? How do they differ from intramolecular forces? What are dipole-dipole forces? How do typical dipole-dipole forces differ from hydrogen bonding interactions? In what ways are they similar? What are London dispersion forces? How do typical London dispersion forces differ from dipole-dipole forces? In what ways are they similar? Describe the relationship between molecular size and strength of London dispersion forces. Place the major types of intermolecular forces in order of increasing strength. Is there some overlap? That is, can the strongest London dispersion forces be greater than some dipole-dipole forces? Give an example of such an instance.arrow_forward
- A 1.50-g sample of methanol (CH3OH) is placed in an evacuated 1.00-L container at 30 C. (a) Calculate the pressure in the container if all of the methanol is vaporized. (Assume the ideal gas law, PV = nRT.) (b) The vapor pressure of methanol at 30 C is 158 torr. What mass of methanol actually evaporates? Is liquid in equilibrium with vapor in the vessel?arrow_forwardExplain why evaporation leads to cooling of the liquid.arrow_forward
