1
Q
what is concentration?
A
the measure of the quantity of a solute dissolved in a quantity of a solution
2
Q
what is the formula for concentration?
A
c = m/v
3
Q
the higher the concentration the more the…
A
solute.
4
Q
the lower the concentration the higher the…
A
volume.
5
Q
what is a fluid?
A
a substance without a definite form that takes the same form as its container.
6
Q
what are examples of a fluid
A
gas and liquid
7
Q
what is a compressible fluid
A
a substance that can change its volume and can be COMPressed (gas)
8
Q
what are three variables that can change a compressible fluid?
A
- number of particles (more particles = more collisions)
- temperature (particles move faster = collisions are harder)
- volume (less space = more collisions)
9
Q
what is a incompressible fluid?
A
a substance thats volume cannot be compressed in a smaller space. (liquids)
10
Q
what are three variables that can change a incompressible fluid?
A
- depth (more mass on the surface)
- volumic mass/density (more masse for the same depth)
- exterior pressure (external pressure is added to the pressure of a fluid)
