Concept explainers
Interpretation:
The reason for liquid in one container evaporates at a faster rate than liquid in other container when both are in same temperature on a table top has to be mentioned.
Concept Introduction:
Evaporation is a process in which the molecules escape from the liquid phase to the gas phase. According to Kinetic molecular theory an evaporation can be explained as, not all the molecules present in a liquid or solid or gas possess the same the same kinetic energy and at any instant, some of the molecules may have above average kinetic energies and other may have below average kinetic energies as a result of collision between molecules. The molecules overcome attractive forces with other molecules.

- Baking Explain why the baking instructions on a boxof cake mix are different for high and low elevations.Would you expect to have a longer or a shorter cookingtime at a high elevation?arrow_forwardThe amount of heat required to melt 2 lbs of ice is twice the amount of heat required to melt 1 lb of ice. Is this observation a macroscopic or microscopic description of chemical behavior? Explain your answer.arrow_forwardA special vessel (see Fig. 10.45) contains ice and supercooled water (both at 10C) connected by vapor space. Describe what happens to the amounts of ice and water as time passes.arrow_forward
- Which processes are endothermic? (a) Condensation (b) Melting (c) Evaporation (d) Sublimation (e) Deposition (f) Freezingarrow_forwardUse vapor pressure. A student leaving campus for spring break wants to make sure the air in his dorm room has a high water vapor pressure so that his plants are comfortable. The dorm room measures 3.01 m x 4.12 m x 3.48 m and the student places a pan containing 0.566L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when he closes the door, and that the temperature remains a constant 21 °C.The vapor pressure of water at 21 °C is 18.7 mm Hg. (a) Calculate the pressure that the water vapor would exert if all of the liquid water evaporated. mm Hg (b) Will all of the water in the pan evaporate? Check&Submit Answer Show Approacharrow_forwardTwo molecules that contain the same number of each kind of atom but have different molecular structures are said to be isomers of each other. For example, both ethyl alcohol and dimethyl ether have the formula C2H6O. CH3-O-CH3 (dimethyl ether) CH3-CH2-OH (ethyl alcohol) 4. Which substance would you expect to be more volatile? A. CH3-O-CH3 (dimethyl ether) В. CH3-CH2-OH (ethyl alcohol) 5. Which would you expect to have higher boiling point? A. ČH3-O-CH3 (dimethyl ether) В. CH3-CH2-OH (ethyl alcohol) 6. Which of the following will explain your answers in # 4 & # 5? A. Ethyl alcohol has higher molar mass than dimethyl ether thus stronger intermolecular forces. B. Hydrogen bond exists in ethyl alcohol while weak dipole-dipole forces exist in dimethyl ether. C. Hydrogen bond exists in dimethyl ether while dispersion forces exist in ethyl alcohol. D. Dimethyl ether has larger surface area than ethyl alcohol.arrow_forward
- The high-pressure phase diagram of ice is shown here. Notice that, under high pressure, ice can exist in several different solid forms. What three forms of ice are present at the triple point marked O? How does the density of ice II compare to ice I (the familiar form of ice)? Would ice III sink or float in liquid water?

How much water (in g) is in the vapor phase?arrow_forward
- The vapor pressure of Substance X is measured at several temperatures: temperature vapor pressure -67. °C 0.0672 atm -55. °C 0.159 atm -43. °C 0.345 atm Use this information to calculate the enthalpy of vaporization of X. Round your answer to 2 significant digits. Be sure your answer contains a correct unit symbol. ☐ ☐ x10 μ ×arrow_forwardYou are a researcher of a manufacturing company of a volatile liquid, such as butanol, ethanol and methanol. Your task is to find out the best container that can store the said chemicals. To do this, you need to identify the intermolecular forces of these substances and relate the intermolecular forces to the rate of evaporation of the substances. You need to relate kinetic molecular model to the behaviors of the substances.arrow_forwardArrange these substances in order of decreasing volatiliity(from most volatile to least volatile) Acetone 17 degrees Celsius, Ethanol 6.8 degrees Celsius , Heptane 7.8 degrees Celsius Hexane 13.6 degrees Celsius Methanol 15.4 degrees Celsius Pentane 18.5 degrees Celsius 1-propanol 3.2 degrees Celsius 2-propanol 7.3 degrees Celsiusarrow_forward
