Lastly you know that the layer$\_$surface$\_$temp is the difference between the temperature of the previous layer $-$ temp$\_$change$\_$per$\_$material. $(2$ pts for calculation, $1$ pt for documentation$)$

Assume the exterior air is at $0$ degrees $C.$

Plot the layer surface temperatures across the different materials as a line graph $($single plot with two lines$)$ for the following cases:
