A

air

B

air +`SO_(2)`

C

pure `O_(2)`

D

air+terpentine vapour

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
Yellow phosphorus glows only at certain partial pressure of `O_(2)`. It does not glow in pure `O_(2)` at one atmospheric pressure. This glow is quenched by certain substances like `SO_(2)` and turpentine.
