Question

Liquid A is known to have a lower viscosity 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 Two 10 L glass flasks are evacuated and sealed. 25.0 mL of Liquid A are injected through the seal into one flask, and 25.0 mL of Liquid B are injected into the other flask. After 30 minutes, the pressures PA and PB inside the flasks are measured. predicted outcome OP A will be greater than PB PA will be less than PB OPA will be equal to PB It's impossible to predict whether p or PB will be greater without more information. V will be greater than VB VA will be less than 1 20.0 mL of Liquid A are poured into a beaker. 20.0 mL of Liquid B are poured into another beaker. After 90 minutes have passed, the volumes V and VB of liquid in each beaker are measured. OVA will be equal to VB It's impossible to predict whether V or Vg will be greater without more information.

Answer 1

vopor pressure is the pressure exerted. by the gas over the liquid phase. Vincocity is a measure of thids. resistance where viscosity is high then intermolecular force of attraction ako be high. on the other hand due to high inter- molecular force of attraction vapor pressure will be loo Der general, con viscous liquid acull have higher vapor pressure. But here 4 is low viscons as well an has low vapor pressure than B' So, for experiment & Grenadines Since Pa fpe au'll be more de pendent on torero vapor pressure. So, Answer: A mill be less than PB for expertment 2: since vapor pressure of ALB So, linad mütt escape more from liquid share to gorous phare at a giren time. So, volume liquid B acill be less than volume of liquida So, & Answer: A nuill be greater than B
