For the following problems for heat conduction in solids, state the: (i) differential equation, (ii) initial condition and/or boundary conditions, and (iii) solution method you would use to obtain answers to the questions below. Write and justify any assumptions that you make in arriving at your conclusions. Note: You do not need to solve the differential equations. (a) A membrane is cured by heating a thin polymer film to a temperature of T₁ throughout the entire thickness of the membrane. Curing is accomplished by sandwiching the membrane between two heated plates, which are brought to a temperature of T₁ at a given time. You are interested in determining how long it will take to heat the entire thickness of the membrane to the temperature T₁. (b) A thick ceramic wall having a thickness 10 cm is used to prevent heat from being transferred from a flash photolysis reactor to the surrounding room. If the thermal diffusivity of the ceramic is 3 x 107 m²/s, answer the following: 1. Is the ceramic material sufficient to prevent measurable heat from being transferred into the room if the photolysis reactor is operated for 1 s? 2. Is the ceramic material sufficient to prevent measurable heat from being transferred to the room if the photolysis reactor is operated for 100 s? 3. Provide an equation for the heat flux into the room if the flash photolysis reactor is operated continuously for several days.

For the following problems for heat conduction in solids, state the: (i) differential
equation, (ii) initial condition and/or boundary conditions, and (iii) solution method
you would use to obtain answers to the questions below. Write and justify any
assumptions that you make in arriving at your conclusions. Note: You do not need to
solve the differential equations.

(a) A membrane is cured by heating a thin polymer film to a temperature of T₁
throughout the entire thickness of the membrane. Curing is accomplished by
sandwiching the membrane between two heated plates, which are brought to a
temperature of T₁ at a given time. You are interested in determining how long it will
take to heat the entire thickness of the membrane to the temperature T₁.
