Two identical 7.5-cm cubes of copper at 425 and 90°C are brought into contact. Assuming that the blocks exchange heat only with each other and that there is no resistance to heat flow as a result of the contact of the blocks, plot the temperature of cach block as a function of time, using the lumped-capacity method of analysis. That is, assume the resistance to heat transfer is the conduction resistance of the two blocks. Assume that all surfaces are insulated except those in contact.

4-7 Two identical 7.5-cm cubes of copper at 425 and 90°C are brought into contact.
Assuming that the blocks exchange heat only with each other and that there is no
resistance to heat flow as a result of the contact of the blocks, plot the temperature
of each block as a function of time, using the lumped-capacity method of analysis.
That is, assume the resistance to heat transfer is the conduction resistance of the two
blocks. Assume that all surfaces are insulated except those in contact.
