Question

Which one of the following statement is false

• A. Work is a state finction
• B. temperature is a state function
• C. Change in the state is completely defined when the initial and final states are specified
• D. Work appears at the boundary of the system

Answer 1

The correct option is A Work is a state finction

Majority carrier in a $n-$ type semiconductor are holes.This statement is false.

Since,in $n-$type semiconductor, the pentavalent impurity atoms donate electrons o the host crystal and the semiconductor doped with donars (pentavalent impurity) is called $n-$type semiconductor.

Therefore majority carrier in a $n-$type semiconductor are electrons
