Reconsider Prob. 18€“79. Using an appropriate software, plot the soil temperature as a function of the distance from the earth€™s surface as the distance varies from 0 to 1 m, and discuss the results.

Data from 18-79

The soil temperature in the upper layers of the earth varies with the variations in the atmospheric conditions. Before a cold front moves in, the earth at a location is initially at a uniform temperature of 10°C. Then the area is subjected to a temperature of €“ 10°C and high winds that resulted in a convection heat transfer coefficient of 40 W/m²·K on the earth€™s surface for a period of 10 h. Taking the properties of the soil at that location to be k = 0.9 W/m · K and α = 1.6 × 10^€“5 m²/s, determine the soil temperature at distances 0, 10, 20, and 50 cm from the earth€™s surface at the end of this 10-h period.
