The growth of a plant is a series of chemical reactions. Are these reactions temperature dependent? Design an experiment to test this factor. Why does growth rate decrease above certain temperatures?
Homework Answers
yes, temperatur eis the primary fector affecting the growth rate in plants.responses to temperature differ among the crop species through out their life cycle and are primarily phenological responces.for example vegitative development increases as temperature raise to species optimum level.
temperature which would be considered extreme and fall below or above cspecific thresholds at critical times during the development can significantly effect the productivity.

You are tasked with evaluating the stirring tank in a chemical plant. The temperature of the inlet stream of the fluid entering the tank is at 300K, has a specific heat capacity of 10 J/(kg*K) and a flow rate of 1 kg/s. The stirrer adds 10 kW power to the system, while an internal cooling coil in the tank removes heat at a rate of 5000 J/s. The line surrounding the pipe of the outlet stream of the fluid exiting...
