A biologist needs to accurately control the defrost cycle for an experiment to properly regulate cell growth. Vials filled with experiment samples are immediately transferred from a cold storage container, held at 0 C, and placed directly into a chamber to slow the rate of heat loss. It takes 6 minutes for the samples in the chamber to reach a stable temperature to within 5% of the surrounding room temperature. The temperature inside the lab is maintained at 25 °C. la) If the scientist wants to examine the samples when they reach 7 C, how long should they wait before removing the samples from the chamber. Clearly indicate the time constant for the system, and the time required. 1b) Plot the time response of the system at one-minute intervals. Clearly label the plot axis, initial condition, and steady state condition. Tabulate the calculated data results for the time response and clearly indicate what temperature the sample will be at 4 minutes after being placed inside the chamber.
