Chapter Nine—Solutions
Diffusion
How does temperature affect the rate of diffusion?
Explore the role of temperature on the rate of diffusion. Set the temperature, then remove the barrier, and measure the amount of time it takes the blue molecules to reach the gas sensor. When the gas sensor has detected three blue molecules, it will stop the experiment. Compare the diffusion rates at low, medium and high temperatures. Trace an individual molecule to see the path it takes.
Osmosis
Press play, and watch the smaller solvent molecules diffuse across the membrane—a process called osmosis! Play with the pore size slider to explore what happens if the pores are too large / small!
Making Solutions
Explore making solutions! Can you make an unsaturated and saturated solution?
