(a)
Interpretation:
The change in vapor pressure of water in a closed beaker has to be predicted when –
- (a) Temperature is lowered
- (b) Volume of the beaker is doubled
- (c) More water is added to the beaker.
Concept Introduction:
When a liquid is boiled, the molecules from liquid phase enter into vapor phase. This phenomenon is called evaporation. Vapor pressure is defined as the pressure exerted by the molecules in the vapor phase of the liquid that is in equilibrium with the liquid phase.

- 5-106 The normal boiling point of hexane, C6H14, is 69°C, and that of pentane, C5H12, is 36°C. Predict which of these compounds has a higher vapor pressure at 20°C.arrow_forwardIn the northern United States, summer cottages are usually closed up for the winter. When doing so, the owners winterize the plumbing by putting antifreeze in the toilet tanks, for example. Will adding 525 g of HOCH2CH2OH to 3.00 kg of water ensure that the water will not freeze at 25 C?arrow_forwardDefine 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_forward
- What term is used to describe a substance that readily evaporates at room temperature because of a high vapor pressure?arrow_forwardPredict which liquid—glycerol, HOCH2CH(OH)CH2OH, or hexane, C6H14—has the greater surface tension. Explain your prediction.arrow_forwardIn terms of their bulk properties, how do liquids and solids differ? How are they similar?arrow_forward
- 5-86 Using the phase diagram of water (Figure 5-20), describe the process by which you can sublime 1 g of ice at-10°C and at 1 atm pressure to water vapor at the same temperature.arrow_forwardWhy do liquids have a vapor pressure? Do all liquids have vapor pressures? Explain. Do solids exhibit vapor pressure? Explain. How does vapor pressure change with changing temperature? Explain.arrow_forwardC. Explain the following occurrences in terms of molecular polarity and intermolecular forces. 1. Propane can be liquefied, the reason why it is produced as liquefied petroleum gas. (a) What intermolecular force is present between propane gases that makes them attract one another and be liquefied? (b) As soon as we open our gas stove, it is immediately converted back to gas state. Explain it in terms of the strength of the intermolecular force present between propane molecules.arrow_forward
- If water were a linear molecule, (a) would it still be polar, and (b) would the water molecules still be able to form hydrogen bonds with one another?arrow_forwardA 2.80−g sample of water is injected into an evacuated 6.00−L flask at 65.0°C. What percentage of water will be vapor when the system reaches equilibrium? Assume ideal behavior of water vapor and that the volume of liquid water is negligible. The vapor pressure of water at 65.0°C is 187.5 mmHg.arrow_forward4. A. Use the list of intermolecular and interparticle forces listed below to account for the following phenomena. Justify your answer in each case. London Dispersion Forces lonic Bonding Dipole-Dipole Interactions Metallic Bonding Hydrogen Bonding Covalent Bonding (i) Nacl has a very high heat of vaporization. (ii) The high volatility of helium (boiling point is - 267 °C, lowest of any element). (iii) What are the strongest attractive forces that must be overcome to boil carbon tetrachloride, (CCl,)? B. Read the following statement: NaF has a higher melting point than F2 because it has a greater molar mass. Do you agree with the statement?
