what factors influence the rate of diffusion? (name 3) |
|
Definition
kinetic energy within atoms and molecules semi-permeable membranes osmotic pressure (from the hypertonic side) |
|
|
Term
Why do solutions with greater concentrations of osmotically active substances have higher osmotic pressures? |
|
Definition
High concentration of the solute means that a high volume of water will attempt to diffuse in; a lot of osmotic pressure is needed to keep this high volume of water from coming in |

Term
What is Brownian movement? |
|
Definition
The intrinsic movement of particles from the passing of kinetic energy from smaller to larger particles. |
|
|
Term
Describe the movement of particles. |
|
Definition
It is random and unceasing. The smaller particles move more than the bigger particles. |

Term
Do the carmine particles exhibit molecular movement? |
|
Definition
They are not actual molecules, but they exhibit molecular movement b/c they are small enough |
