Molecules move by osmosis, diffusion, and active transport.
OSMOSIS
Osmosis moves water from an area of high concentration to an area of lower concentraion.
ACTIVE TRANSPORT
Active transport moves sodium, calcium, and potassium from an area of low concentration to an area of higher concentration using energy.
DIFFUSION
Diffusion moves other molecules from high to low concentraion.

How does heat make molecules move?
The heat energizes the molecules.The molecules of air will move here and there as they are free. Molecules of solids vibrate at there place.Due to heat the molecules get energized that is the main thing.
How do molecules in air cause air resistance?
Molecules get in the way. When something passes through the air, it has to move molecules out of the way, and they are usually pushed aside.
How do you think the molecules move in hot and cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
How does warm air molecules move?
The molecules in warm air move faster
How do ice water molecules differ from warm water molecules?
The main difference is that ice water molecules have very low kinetic energy, i.e. they don't move very fast, compared to warm water molecules. The other difference is in the intermolecular forces holding the molecules together. They are greater in ice than in warm water.

Is diffusion the main method by which small molecules move into and out of cells?
Yes.
Which way do water molecules move?
because its a liquid.

Which way do the water molecules move when salt is poured on a snail?
in
What directions do molecules move if the concentration is equal on both sides of a membrane?
they should move neither way. Rather, some molecules will move either side, but the concentration will stay the same
When an egg is placed in vinegar which way do th water molecules move?
Hi!! I am pretty sure the water molecules move outwards from the egg. This is called osmosis.
What are the two main kinds of movement that happens into and out of the cell?
Ions and molecules move into and out of the cell by two main methods:Passive transport does not require any energy. Molecules wither diffuse into the cell or enter the cell via transporter proteins located on the cell membrane.Active transport requires the use of ATP molecules to move ions or molecules into and out of the cell.
What can cause molecules to move faster?
Applying heat is one way to achieve this.
In what way are liquids and gases different?
The molecules of liquid are loosely packed but they can not move out of the container their movement is restricted to the cotainer only but the molecules of gases can move freely without any restriction.
Which way would the water molecules move if salt is poured on snail?
Water would move OUT of the snail and onto the salt.
How do molecules move in fluid?
Molecules move in a fluid the same way they move through anything else. If the fluid is warmer, they move faster.
