Okay, you answered all correctly...

The challenge is then, why do these things occur (eg why does hot air go up, why doesn't oil and water mix, etc),

Default oil and Water

When you put water and oil in a beaker together, the water will float to the top, while the oil will sink to the bottom. This is because oil has a greater density than water.

Actually, this has always been a misinterpretation. Water is DENSER than oil. Oil floats ON water. (Water is one of the most dense liquids.)

Default Strange

I think you may be mistaken, because after I posted this, I tried the expiriment myself and the water floated on the oil. This proves that oil is denser. But who knows?
