Question: A 2m x 2m x 300mm wall is made out of fireclay brick. The thermal conductivity is 0.05 w/mk. The Cp is 560 J/kg

A 2m x 2m x 300mm wall is made out of fireclay brick. The thermal conductivity is 0.05 w/mk. The Cp is 560 J/kg C. The inner wall temperature goes from 25C to 1650C. There is 300 kWh of energy input on the inner wall to heat up the wall from 25C to 1650C. What will the outer wall temperature be? How much energy will the wall absorb? How long will it take the wall to heat up?
