the experimental set up shows the change in the color after copper sulfate crystals are put into a beaker of water. observations verify that\na particle motion results in a rapid rate of diffusion.\nb water molecules move as a result of active transport.\nc stirring is necessary to dissolve the copper sulfate in water.\nd copper sulfate spreads out through the water as a result of diffusion.
Answer
# Brief Explanations:
- Diffusion is the movement of particles from an area of high concentration to an area of low concentration. In this experiment, copper sulfate particles spread out in water without stirring (so option C is wrong).
- The rate of diffusion shown here is not rapid (so option A is wrong).
- Active transport requires energy and is not relevant here as water molecules are not moving via active transport (so option B is wrong).
- Copper sulfate spreads through water due to diffusion as particles move from where they are more concentrated (near the crystals) to where they are less concentrated (the rest of the water).
# Answer:
D. copper sulfate spreads out through the water as a result of diffusion.
