Consider two blocks of nickel, treated as semi-infinite
solids. Initially, one block is at 0 C and the other 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. Use _Nickel = 2.3E-5 m2
