|
what is the force of attraction? |
how strong particles are attracting |
|
|
what are the three forces if attraction? |
strong, medium, weak |
|
|
what is particle spacing? |
how far particles are from each other |
|
|
if bio steel was put into water, why does it dissolve without stirring? |
particles are always moving, water is a universal solvent, the force of attraction is really high so it attracts the other particles from the bio steel |
|
|
what is waters special feature? |
can expand when freezes, doesn’t have a specific form (takes the shape of the container) |
|
|
definition of fluid |
any substance that flows |
|
|
definition of slurry |
a mixture of solids and liquids |
|
|
definition of matter |
anything that has a mass and volume |
|
|
definition of volume |
measurement of how much space a substance takes up |
|
|
definition of thermal expansion |
increase in the volume of a substance in response to an increase in its temperature |
|
|
viscosity |
the resistance of a fluid to flow |
|
|
flow rate |
measurement of the speed at which a fluid flow from one point to another |
|
|
density |
amount of mass contained given volume |
|
|
what is the 6 particle the theory of matter? |
1. all matter is made up of tiny particles. 2.all particles are in a constant motion. 3. all particles of one substance are identical. 4. temperature affects the speed at which particles move 5. in liquids and solids, the particles are close together and have stony forces of attraction between them 6. in gas there are spaces between the particles |
|
|
name three ways on how to put liquids to work |
can hold materials, can transport solids, and can form into other shapes |
|
|
why does steel have to go through a liquid phase? |
it can be easier to shape, transportation is easy |
