Assume that the diffusion coefficient of glucose is 5.70 × 10−7 cm2/s. calculate the time it would take for a glucose molecule to diffuse 11.3 μm.

The diffusion coefficient of glucose is . Glucose molecule diffuse to , time for diffusion can be calculated as follows:

To calculate the time first convert x into cm

Also,

Thus,

and,

Putting the values,

Therefore, time taken for diffusion will be 1.12 s.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
