A) the electrical and thermal conductivities both increase
B) the electrical and thermal conductivities both decrease
C) the electrical conductivity increases but thermal conductivity decreases
D) the electrical conductivity decreases but thermal conductivity increases
Correct Answer: B
Solution :
As the number of electrons increase, their number of collisions, increasing the thermal and electrical resistance. Hence,electrical and thermal conductivities both decrease.You need to login to perform this action.
