Evaporation of a perfume occurs due to the small, lipophilic, and highly volatile nature of the fragrance compounds in its mixture. To increase the longevity and durability of the perfume, synthetic additive materials are added to reduce the evaporation rate. In an experiment to study the impact of adding synthetic additives to the evaporation rate of a perfume, it was found that the evaporation rate, v in l/hr, can be represented using the following equation: Perfume without the addition of synthetic additives: v = 5t + 0.02 where t is the time in hours (hr). (b) Using numerical differentiation of order O(h) only, estimate the instantaneous rate of change of the evaporation rate with respect to time from t = 0 hours to t = 10 hours with a step size of 5 hours for both conditions - with and without additive materials.
