Does a higher density affect freezing time?

Question

I quickly need to know if a higher density will freeze quicker or slower than a lower one. If it is possible, list these in order from quickest freezing time to slowest freezing time.

Tap Water
Salt Water
Sugar Water
Vegetable Oil

Answer 1

Density has no effect on freezing point, its the admixtures present.

Rate of freezing is proportional to specific heat.
