7. Temperature vs. time data were taken for a small aluminum sphere (diameter of 0.80 cm; heat capacity of 902 J/kg-K,density of 2830 kg/m³). It was initially at T; =

185 °C when it was placed in a wind tunnel at T, = 27 °C. Given the Temperature (T) and time (t) data below, use a spreadsheet and plot a graph of appropriate variables so that you can insert a trendline and fit the data to a linear curve. Use the equation from the curve fit to determine the convective heat transfer coefficient for the air in the wind tunnel, h.
