Why resistivity of semiconductor decreases with increase in temperature ?

Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at 100^@ C, while the other one is at 0^@ C. If the two bodies are brought into contact, then assuming no heat loss the final common temperature is _____
