Consider two blocks treated as semi-infinite solids. One
block is made of copper and the other of stainless steel. Initially, the block
made of copper is at 0 C and the block made of stainless steel at 100 C. We now
bring these blocks in contact. Ignore the contact thermal resistance and find
the temperature of a point located 5 cm from the common boundary in either
block, 5 minutes after the contact.
