Correct answer: B. 360°C
- A. 260°C
- B. 360°C
- C. 630°C
- D. 620°C
Explanation
The correct answer for the sublimation temperature of P2O5 is:(b) 360°C.P2O5, also known as diphosphorus pentoxide, is a white, hygroscopic powder highly reactive to water.It sublimes directly from solid to gas without passing through a liquid phase at around 360°C under atmospheric pressure.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
