Understanding the Statements
In the context of semiconductors and conductors, let's analyze the statements Y and Z.
Statement Y: Resitivity of a Semiconductor
- The resistivity of a semiconductor indeed decreases with an increase in temperature.
- This happens because, as temperature rises, more charge carriers (electrons and holes) are generated in the semiconductor, enhancing its conductivity.
Statement Z: Collisions in Conducting Solids
- In a conducting solid, the rate of collisions between free electrons and ions increases with an increase in temperature.
- Higher temperatures cause ions in the lattice to vibrate more vigorously, leading to more frequent collisions with free electrons, thus influencing the material's conductivity.
Relationship Between Y and Z
- The reasoning behind the decrease in resistivity (statement Y) can be connected to the increase in collision rates (statement Z).
- As temperature rises, while the number of charge carriers increases (improving conductivity), the increased collision rate could suggest an opposite effect. However, the net effect in semiconductors is that the increase in carriers outweighs the impact of collisions.
Conclusion
- Both statements are true:
- Y accurately describes the behavior of semiconductors with temperature changes.
- Z correctly identifies the behavior of conducting solids under temperature variations.
Thus, the correct answer is option 'C': Both Y and Z are true.
