TODAY, let’s find out…WHAT happens in our body to our cells when we drink too much salt??

Diffusion date

Diffusion: when a solution spreads out everywhere.This happens by itself because particles can naturally move around (vibration, rotation, translation of atoms)

Trying to make EQUAL CONCENTRATION.

We will learn about osmosis of the solvent WATER.

Osmosis date

Osmosis date

Osmosis: is the diffusion of a LIQUID SOLVENT,going through a semipermeable membrane.

We will learn about WATER only in this class.

Osmosis date

Osmosis: is the diffusion of a LIQUID SOLVENT,going through a semipermeable membrane.

We will learn about WATER only in this class.

Osmosis date

Membrane:

Osmosis date

Membrane: wall, barrier. Stops things from passing through.

Osmosis date

Membrane: wall, barrier. Stops things from passing through.

Permeable membrane:

Osmosis date

Membrane: wall, barrier. Stops things from passing through.

Permeable membrane: wall that allows liquids to pass through.

Permeable membrane: wall that allows liquids to pass through.

Semipermeable membrane:

Osmosis date

Membrane: wall, barrier. Stops things from passing through.

Permeable membrane: wall that allows liquids to pass through.

Semipermeable membrane: wall that allows ONLY CERTAIN liquids to pass through.

Osmosis date

Membrane: wall, barrier. Stops things from passing through.

Permeable membrane: wall that allows liquids to pass through.

Semipermeable membrane: wall that allows ONLY CERTAIN liquids to pass through.In osmosis of water, only water can pass through!
