1.) About how long will it take a perfume molecule to diffuse a distance of 8.00 m in one direction in a room if the diffusion constant is 1.000 10-5 m2/s? Assume that the air is perfectly still—there are no air currents. In seconds

2.) The reaction rate for the prepupal development of male Drosophila is temperature-dependent. Assuming that the reaction rate is exponential as in, reaction rate e−Ea/(kT). The activation energy for this development is then 2.81 10-19 J. A Drosophila is originally at 6.20°C and it's temperature is increasing. If the rate of development has increased 3.3%, how much has its temperature increased? In Celsius

3.) How much heat is required to raise the body temperature of a 50.0-kg woman from 37.0° C to 38.4° C? In kcal
