Consider a slab of copper which has a thickness of 25 cm and anarea of
90 cm2 which separates two environments with differenttemperatures.
Initially environment A has a temperature of 125oC and environmentB
has a temperature of 10oC.
(Thermal conductivity of Copper = 400 W/m K)
a. Determine the initial rate of energy transfer through theslab?
b. Sketch the temperature of environment A as a function oftime.
Only changes due to heat transfer through the slab should be
considered.
c. On the same sketch draw the temperature of environment B asa
function of time.
d. Explain the form of the sketches.
