Liquids have volume but do not Liquids have volume but do not form a shape. form a shape.

particles in liquidsparticles in liquids

• particles are semi-closeparticles are semi-close

• they can movethey can move

surface tensionsurface tension

• a pull or force in liquids which causes the a pull or force in liquids which causes the molecules on the surface to become molecules on the surface to become closer togethercloser together

• If water was dropped on a leaf it would If water was dropped on a leaf it would bead up and pull slightly together because bead up and pull slightly together because water molecules attract each otherwater molecules attract each other

viscosityviscosity

• a fluid that resist the force tending to a fluid that resist the force tending to cause the fluid to flowcause the fluid to flow

• liquids with a high viscosity flow more liquids with a high viscosity flow more slower (ex. honey) slower (ex. honey)

• liquids with a low viscosity flow more liquids with a low viscosity flow more quicker (ex. vinegar and water)quicker (ex. vinegar and water)

Gas do not form a shape or Gas do not form a shape or volume. volume.

Particles in GasParticles in Gas

• is considered a fluidis considered a fluid

• does have pressuredoes have pressure

• separate as it movesseparate as it moves

volumevolume

• the amount of space that matter fillsthe amount of space that matter fills

• particles move and fill all available spaceparticles move and fill all available space

• value of gas is the same as the volume of its value of gas is the same as the volume of its container container

Helium inside a container is Helium inside a container is compressed or pressed together compressed or pressed together tightly to fit into a metal tank. If tightly to fit into a metal tank. If balloons are blown up with this helium balloons are blown up with this helium it expands to fill them making the it expands to fill them making the volume greater than the volume in the volume greater than the volume in the tanktank

pressurepressure

• The force of an outward pushThe force of an outward push
