A hot plate is placed in contact with a cold plate of a different thermal conductivity as shown in the figure.
The initial temperature (at time 𝑡=0) of the hot plate and cold plate are Tₕ and T_C , respectively. Assume perfect contact between the plates.
Hot PlateSurface S
Cold PlateWhich one of the following is an appropriate boundary condition at the surface S for solving the unsteady state, one-dimensional heat conduction equations for the hot plate and cold plate for 𝑡 > 0?
Options
- A.Temperature at S is same for both the plates
- B.Gradient of temperature at S is same for both the plates
- C.Gradient of temperature vanishes at S
- D.Temperature at S is the average of Tₕ and T_C (2 Marks)
