KEY TAKEAWAYS

• Water does not dissolve oil, because oil is non-polar.
• Oil floats on top of water as they do not dissolve each other for the reason that polar dissolves polar and when a non polar substance is introduced the water sticks together and does not allow it to enter the inter molecular spaces in between hence the liquids become immiscible essentially not mixing
• Alcohol is Polar as is water, and like dissolves like hence when water is added to alcohol the volume does not really increase as water is being dissolved.
• The Dipoles in water create the bonding between molecules of water creating the sliding of molecules over each other as well as the cohesion which eventually causes surface tension which allows for over filling as the bonds attract and keep the layer above the rim from falling or spilling.
