Answer:

smoke
marshmallow
paint
Body spray

Explaination:

Firstly, what are colloids?

Colloids are a mixture of two substances:

one of those substances are insoluble and inseparable

There are 4 types of colloids:

Sol- Solid in a liquid
Emulsion- Liquid in a liquid
Foam- Gas in solid/liquid
Aerosol- Solid/liquid in gas

So on to the answers:

Smoke consists of solid and gas and since the solid is being carried by the gas, it is a solid in a gas (aerosol)
Marshmellow consists of tiny air bubbles and sugar(solid), the air bubbles is inside the solid making it a gas in a solid (foam)
Body spray turns gas into liquid after spraying it through the can, making it a liquid in a gas (aerosol)
Paint dries up to become solid which makes it a solid is a liquid (sol)

Hope y'all understand

lana [24]

Gasoline is predominantly octane, C8H18. Something like soap would be a great homogenizer. Soap is composed of a long hydrocarbon chain with a tiny, highly polar tip on one end. Usually, the soap is the anion of a salt, NaX. This allows the polar end of the soap to stick to water, while the nonpolar end sticks to the oil.

$\frac{kg*m*m}{m^3*s*\mu}=1=\frac{kg}{m*s*\mu}$

Is there an optimum amount of baking soda and vinegar to put in a plastic soda bottle rocket? How would you figure that out?

Snezhnost [94]

Add 1 tsp. of vinegar to the canister at a time, filling it almost to the top. You need to add as much vinegar to the canister as possible without the vinegar and the baking soda coming into contact when you later snap the lid onto the canister. Depending on the exact canister, this may be around 5 tsp.

The weight of the body in the air is .... the weight of the submerged body

stira [4]

Answer:

the correct answer is option 'b': More than

Explanation:

The 2 situations are represented in the attached figures below

When an object is placed in air it is acted upon by force of gravity of earth which is measured as weight of the object.

While as when any object is submerged partially or completely in any fluid the fluid exerts a force in upward direction and this force is known as force of buoyancy and it's magnitude is given by Archimedes law as equal to the weight of the fluid that the body displaces, hence the effective force in the downward direction direction thus the apparent weight of the object in water decreases.
