There is a hemispherical naphthalene in a laboratory bench. The height of lab ceiling from the lab bench is 2.5m and the initial radius of naphthalene sphere is 0.1m. The students in the lab observe the change in the radius of naphthalene hemisphere and record the data as shown below: Radius (cm) Time (min) 10 1 8 3 3 4 2 0.5 7 By using the data above determine the diffusivity of naphthalene in air and compare with the value you have found by a semiemprical equation. And determine the concentration of naphthalene 1 m above the bench.
