Question $2$

The initial temperature of an iron bar is zero $(T=0C)$ for all points on the bar, except at $x=0\mathrm{.}0m$ as shown in Figure $1.$ The bar is heated at $x=0\mathrm{.}0m$ where the temperature is kept at $T=8C$ at all time. The bar is fully insulated. Therefore, the temperature at the other end of the bar is always same with the temperature at its neighboring point at $($:$x=1\mathrm{.}0(m)$
