Liquid own to have a higher vapor pressure and higher viscosity than Liquid Y. Use these facts to predict the result of each experiment in the table below, if you can. experiment predicted outcome Ox will be greater than ty Olx will be less than ty 25.0 mL each of Liquid X and Liquid Y are poured through a funnel, and the times tx and ty needed to pour each liquid through the funnel are measured. otx will be equal...
Liquid water in a closed container at 25 degrees C is in equilibrium with water vapor at a pressure of 0.0313 atmospheres. Consider a puddle on a sidewalk at 25 degrees C. If the relative humidity is 38% (i.e., the H2O(g) partial pressure is 0.012 atmospheres) what is the free energy change for evaporation of water from the puddle?
A liquid placed in a closed container will evaporate until equilibrium is reached. At equilibrium, which of the following statements is false? A. The partial pressure exerted by the vapor molecules is called the vapor pressure of the liquid. B. Liquid molecules are still evaporating. C. The number of vapor molecules remains essentially constant. D. The partial pressure of the vapor is constant. E. The boundary (meniscus) between liquid and vapor disappears.
We put a mixture of helium, oxygen and nitrogen gases in a closed container at 25 ° C. Container pressure in this case is 300 kPa. By a process, we remove all helium gas in the mixture from the closed container. Container pressure in this case reaches 250 kPa. What percentage of the gas mixture did the initial mixture of helium molecules contain? If there are 14 grams of nitrogen and 32 grams of oxygen in this container, what is...
17. When a liquid sample is taken from sea level to a higher elevation, what happens to the external (atmospheric) pressure on the liquid and the boiling point of the liquid? A) Both decrease. B) Both increase. C) Pressure goes down but boiling point goes up D) Pressure goes up but boiling point goes down. 18. In comparing gases with liquids, gases have A) greater; smaller B) greater; greater C) smaller; smaller D) smaller; greater E) none of the above...
1.A gas container is initially at 47 mm Hg and 77 K (liquid nitrogen temperature.) What will the pressure be when the container warms up to room temperature of 25 ˚C?
Use the References to access important values if needed for this question. The vapor pressure of liquid octane, CgH1s, is 100. mm Hg at 339 K in a closed, evacuated 544 ml container at a temperature of 339 K. It is found that all of the CgHis is in the vapor phase and that the pressure is 61.0 mm Hg. If the volume of the container is reduced to 345 ml at the following statements are correct? constant temperature, which...
A gas sample in a closed, expandable container of intial volume 5 00 L was ailowed to warm from 25 "C to 35 C, at constant moles and pressure. What was its new volume? Select one A. 4380 L A sample of hellum gas at 27.0 "C and 3 60 atm pressure is cooled in the same container to a temperature of -73.0 °C. What is the new pressure? Select one: A. 4.15 atm
If heat is added to ice and liquid water in a closed container and, after the addition of the heat, ice and liquid water remain, a. the vapor pressure of the water will decrease. b. the temperature will increase somewhat. c. the temperature will decrease somewhat. d. the vapor pressure of the water will rise. e. the vapor pressure of the water will remain constant.
The answer is B .Why ?
28. For a gas in a closed container its pressure is found to be 400 N/m2 at 27°c. If the temperature were raised to 54°c, what would the pressure become? A) 800 N/m2 B) 436 N/m2 c) 200 N/m2 D) 427N /m2
