Assuming the following materials will not mix, show how the materials would "stack up" in a graduated cylinder.
air 0.001g/cm3, gycerin 1.26g/cm3,corn syrup g/cm3,wood 0.85 g/cm3,steel7.81g/cm3,rubber 1.34 g/cm3,ice0.94 g/cm3,water 1.0 g/cm 3
corn oil 0.93g/cm3

Density is mass per unit volume.

Its formula is  

Density = Mass / Volume

Its units can be kg/L  or kg/() or g/mL or g/()

Density of various substances are given. The more denser substance goes to the bottom of the graduated cylinder.  

Air on the top then comes  Wood followed by  Corn oil followed by  Ice and then  Water followed by  Glycerin then  Rubber then  Corn syrup and at last  Steel at the bottom  which will more denser than all the substances mentioned above.

The staking up of the substances is in the order mentioned below in the tabular column

The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different.  let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones).  now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. if you put both of them in the freezer, the one that started out colder will freeze first.  for the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. imagine putting one outside on a really really cold day in georgia, and having a friend in alaska put one outside on the same day. since it would be so much colder in alaska, the glass of water there would freeze before yours.  so, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in georgia.
