Liquid A is known to have a lower surface tension and lower vapor pressure than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment Identical wire loops are dipped into Liquid A and Liquid B, so that a film of liquid forms across the loops (like the bubble solution on a child's bubble blowing wand). The width of each loop is increased slowly and the forces F and F3 needed to make the loops 5% wider are measured. Small amounts of Liquid A and Liquid B are sprayed into the air, where they form perfect spheres with a volume of 45.0 μL. The diameters of these drops are measured with a high-speed camera, and their surface areas Sand S calculated. predicted outcome Fwill be greater than F OF will be less than F OF will be equal to FB It's impossible to predict whether For F will be greater without more information. OS will be greater than S S will be less than S OSA will be equal to SB It's impossible to predict whether Sor S will be greater without more information.

The temperature of 1.9 kg of water is 100.0°C, but the water is not boiling, because the external pressure acting on the water surface is 3.0 x 105 Pa. Using the vapor pressure curve for water given in the figure, determine the amount of heat that must be added to the water to bring it to the point where it just begins to boil.

This question is not a grade question, its just a pratice problem.
Liquid X is known to have a lower vapor pressure and lower surface tension than Liquid Y. Use these facts to predict the result of each experiment in the table below, if you can. experiment 40.0 mL of Liquid X are put in one sealed 5 L flask, and 40.0 mL of Liquid Y are put in another sealed 5 L flask. The pressure in each fisk is slowly increased by pumping in argon gas. A 250 mL beaker is submerged in a large. container of Liquid X and turned upside down, and another 250 mL beaker is submerged and turned upside down in a large container of Liquid Y. Hydrogen (H₂) gas is bubbled into each upside-down beaker until 100 mL of liquid has been displaced. The masses my and my of hydrogen inside each beaker is then chemically determined. Note for advanced students: you may assume the solubility of H₂ in either liquid is very low. O predicted outcome Eventually both liquids boil, X first and then Y. Eventually both liquids boil, Y first and then X. Neither liquid will boil. It's impossible to…
