Two equal mass objects (which are in thermal contact) make up a system that is thermally isolated from its surroundings. One object has an initial temperature of 100C and the other has an initial temperature of 0C.
 
  What is the equilibrium temperature of the system, assuming that no phase changes take place for either object? (The hot object has a specific heat capacity that is three times that of the cold object.) A) 23C
  B) 19C
  C) 75C
  D) 50C
  E) 25C

  B) 5.6  10-8 N/C
  C) 5.8  10-8 N/C
  D) 6.0  10-8 N/C

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
