OADVANCED MATERIAL Understanding consequences of important physical properties f 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 predicted outcome 20.0 mL of Liquid A are poured intoa beaker. 20.0 mL of Liquid B are poured into another beaker. After 90 minutes have passed, the volumes V and Vg of liquid in each beaker are measured V4 will be greater than V VA will be less than oV, will be equal to V OIt's impossible to predict whether V, or Va will be greater without more information. O A will form a layer on top of 8 B will form a layer on top of A 30.0 mL of Liquid A and 30.0 mL of Liquid B are mixed together in a small beaker, and The tiquids will form a homogeneous mixture let stand for 30 minutes. It's impossible to predict whether the liquids wi mix without more information esc E93

Explanation / Answer

Liquid A has lower viscosity and lower vapour pressure

So in first case, liquid A has lowe vapour pressure so it will forms less amount of vapour at same time as B, so volume of liquid A is greater.

Here vapour pressure defind as , pressure applied on liquid by its own vapour at equilibrium.

2 nd case,

Answer is impossible to.predict because no information about nature of liquid and also densities .
