If possible, can you explain what the other two plots are also?

Consider the following plots of temperature distribution in a solid of thickness L, which one represents an adiabatic boundary condition? (Circle your answer)

Solution

Figure b-

Adiabatic boundary condition: answer is figure- b

No heat transfer at x=0 there will be max temperature or slope is zero at x=0 I.e dT/dx=0

Figure a

-two sides of the Wall are maintaining at different temperatures

@ x=0. T=T1

@ x=L. T=T2

These are surface boundary condition

Figure-c

Convection boundary conditionsheat is convected to surrounding from both surfaces but both surfaces are with different convection boundary condition
