## How do you explain density in an experiment?

An object’s density is calculated by dividing its mass (weight) by its volume (the amount of space it occupies). Liquids have density too. This experiment uses several different types of liquid to determine which is more dense. Lighter liquids are less dense than heavier liquids so they float on top of them.

How do you make a 3 layer density tower?

Make a bubbling density tower! Pour corn syrup, vegetable oil and water into a cup to form 3 layers. Add a few pieces of Alka Seltzer. It will sink to the water and make bubbles, making the layers swirl and mix for a while before settling back into their layers.

### How does density work?

Density is calculated using the following equation: Density = mass/volume or D = m/v. If we take the same volume (one cubic centimetre) of foam, wood and concrete, we can see that each has a different mass. Less Dense, More Dense. If something is heavy for its size, it has a high density.

How does density work in liquids?

The density of a liquid is a measure of how heavy it is for the amount measured. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is more dense. If a liquid that is less dense than water is gently added to the surface of the water, it will float on the water.

#### What floats between water and oil?

Alcohol floats on oil and water sinks in oil. Water, alcohol, and oil layer well because of their densities, but also because the oil layer does not dissolve in either liquid. The oil keeps the water and alcohol separated so that they do not dissolve in one another.

Can you shake a density column?

Density columns have many layers of liquids that sit on top of each other, but if you accidentally mix them up, most will settle into just two layers. You can shake this one all day long—it will always return to its original three layers.

## How do you find the density of oil?

If the weight of the oil was measured in ounces, convert this to grams by multiplying by 28. Thus, 2.0 ounces would be 2.0 x 28 = 56 grams. Calculate density by dividing the mass in grams by the volume in milliliters.

How do you perform a water in oil density experiment?

Whether you’re performing a water in oil experiment on your own, in your classroom or in front of a crowd, it really doesn’t matter — this oil and water density experiment can be pretty messy. If you’re in a performance setting and time matters, use four identical containers; then, fill two with oil and two with colored water in advance.

### What are the densities of the liquids used in the column?

Here are the densities of the liquids used in the column, as well as other common liquids: MATERIAL DENSITY (g/cm 3 or g/mL) Rubbing alcohol 0.79 Lamp oil (refined kerosene) 0.81 Baby oil 0.83 Vegetable oil 0.92

How do you not make a mess with water in oil?

With oil and water experiments, there really is no way to NOT make a mess with this activity. Whether you’re performing a water in oil experiment on your own, in your classroom or in front of a crowd, it really doesn’t matter — this oil and water density experiment can be pretty messy.

#### What is the oil formation volume factor (Bo)?

The Oil Formation Volume Factor, Bo, is comparable to the water formation volume factor. It relates volume of 1.0 STB of crude oil at stock tank conditions, p ST and T ST, to its volume at reservoir conditions, p r and T r. A typical plot of B o is illustrated in Figure 3.10.
