Correct Answer – c

Correct Answer – C

Correct Answer – C
`T_(2)O_(2)` can begave as conductor or insulator depending upon the temperature.

Correct Answer – C
`TiO_(3)` behaves as conductor or insulator depending on temperature because of variation of energy gap between valence band and conduction bond with the variation of temperature.

Correct Answer – C
Certain metal oxides like `VO_(2),VO,VO_(3) and TiO_(3)` show metallic or metallic or insulating property depending upon temperature As, temperature Varius metallic or insulating property varies this is due to vartation in energy gap between conduction band and valence band .
