CURVE FITTING OF HEAT CAPACITY OF GAS 1. By using a data given in Table 1, create the data in excel file. 2. Then Create a MATLAB® script to compute a best-fit 1st order, 2nd order, 3rd order and 4th order for the data and evaluate the fitted data using a new temperature given as follow :- new_temp = 250 T to 1500 T with increment of 10 T. 3. Plot them on the same graph. 4. Based on your observation, which model best represents the data? (1st order, 2nd order , 3rd order or 4th order). Then display your polynomial equation. 5. Then, create a short report to present your findings. Please include all the codes, graphs and screenshot of excel files in your report. Make a virtual presentation via pre-recorded video less than 15 minutes for each group. Every member of the group must present his or her part in the video. You and the slide must be in the video. 6. 7.
