Question

Experimental results about diffusion depends on temperature


Solution

Procedure: Temperature Difference
  1. Fill one glass cup with hot water. Fill the second glass cup with cold water.
  2. Drop 1-2 drops of red food coloring in the hot cup, and 1-2 drops of blue food coloring in the cold in the cold one.
  3. Watch and wait for color to disperse entirely.
Observations & Results

You should have noticed that the red food coloring in the hot water dispersed much more quickly than the blue food coloring in the cold water did. This is because particles vibrate faster and harder when they’re warmer—the hot water molecules struck the food coloring molecules harder and more frequently, scattering them until the cup ended up containing a homogeneous solution.
