Properties of liquids

1. PROPERTIES OF LIQUIDS

2. IN THIS PRESENTATION
• Shape
• Compressibility
• Volume
• Strength of IMFs
• Type of particle motion

3. SHAPE OF LIQUIDS
• Liquids have no definite shape
• They take the shape of the container (when you place liquids in a container
they follow the outline of the container to the level of their level)
• This shows that liquids can flow freely

4. COMPRESSIBILITY OF LIQUIDS
• Liquids are slightly compressible
• You can slightly squeeze a liquid in a container
• This happens since they have some space between the particles
• You can not squeeze liquids for a long time since shortly after, the partcles
get close together
• This means overall, liquids are incompressible.

5. VOLUME
• Liquids have a fixed volume
• Placing a liquid in a small container makes the liquid reach a higher level
than in a larger container.
• This happens because the liquid maintains the space it occupied in the
bigger container
• This is why a liquid overflows when the space inside the container is not
enough for it.

6. STRENGTH OF IMFS IN LIQUIDS
• Intermolecular forces (IMFs) are the attraction forces holding molecules
together in a substance.
• In liquids, the IMFs are fairly strong hence there is some flexibility in the
molecules of a liquid.
• Thus liquids can flow – when you place a liquid on a flat surface it spreads
over the surface.

7. TYPE OF PARTICLE MOTION
• In liquids, the molecules are slightly free to move.
• They do not move from one place to another necessarily.
• Molecules of a liquid slip and slide over each other.
• This is so since the IMFs between the molecules are limited hence allowing
the molecules to slip over each other.
