Challenge Problems
Push your limits with advanced challenges
If the diffusion coefficient for a certain dye in water is found to be 1.0 x 10⁻⁵ cm²/s at 25°C, what would it be at 50°C, given that D approximately doubles with every 10°C increase? Show your calculations.
💡 Hint: Use the doubling rule for every 10°C increase.
Design an experiment to compare the diffusion coefficients of two different dyes in agarose gel. Describe the setup, the measures you would take, and the data you would collect.
💡 Hint: Focus on maintaining constants while varying only the dye.
