Is flour a liquid or a solid?

Is flour a liquid or a solid?

Although flour can be poured and takes the shape of a container you put it in, flour is in fact a solid. Flour is a powdered version of it’s original state, raw grains.

What type of matter is flour?

solid matter

How do you know flour is solid?

Flour does have a definite shape if you look at the individual grains. I think flour is a solid. It does have a definite volume, mass and shape. It acts like a liquid because the grains are so small especially when they are mixed with air.

Is corn flour a solid liquid or gas?

The science behind it all: The cornflour-water mixture is an example of a non-Newtonian fluid. Newtonian fluids, such as water, maintain a constant viscosity (the measure of a fluid’s resistance to flow) unless the temperature or pressure changes.

Is an egg solid or liquid?

Because the inside of a cooked egg is solid, the particles within it cannot move around relative to one another or the shell. So all of the inside particles move in unison, along with the shell. In a raw egg, however, the inside is still liquid.

Can you drink Oobleck?

Luckily, the gooey substance is not toxic, but it probably won’t taste good since it’s just cornstarch and water. As one individual pointed out on Yahoo Answers, while eating oobleck may not be poisonous, it could potentially give someone pains in their stomach if large quantities are ingested.

Is Oobleck dangerous?

Oobleck is non-toxic, but please use caution when doing any science activity. Be careful not to get it in your eyes, and wash your hands after handling the Oobleck.

Can you get stuck in Oobleck?

Homemade Cornstarch Quicksand (Oobleck) Quicksand is a non-Newtonian fluid. Its viscosity changes based on how much force is being applied and at what speed the force is being applied. Oobleck and quicksand have another similarity, they both can trap people.

Can Oobleck get moldy?

Oobleck can be kept in an airtight container for 24 hours, but may require more water before it becomes the right consistency again. Dispose of Oobleck after 24 hours or it can develop mold.

Does Oobleck need to be refrigerated?

Once oobleck dries it returns to a cornstarch powder that can be easily swept or vacuumed up. To store oobleck let it dry out in a bin open to the air, then refresh it with water when ready to use again. I tried storing it in an airtight container and after few days it spoiled.

What else can you add to Oobleck?

• Add color to water. Whisk the food coloring into the water so that it colors the oobleck evenly.
• Add cornstarch. Then stir in the cornstarch. Start with 1.5 cups and add more if it is too runny. That’s it!

Why does Oobleck turn into a liquid?

In oobleck, the relatively large solid cornstarch molecules form long chains. The smaller water molecules flow past each other and between cornstarch molecules allowing the chains to slide and flow around each other. This is why oobleck behaves like a liquid when it is not under pressure.

What is an example of a non-Newtonian fluid?

An inexpensive, non-toxic example of a non-Newtonian fluid is a suspension of starch (e.g., cornstarch) in water, sometimes called “oobleck”, “ooze”, or “magic mud” (1 part of water to 1.5–2 parts of corn starch).
