Question

(D)Water was poured over a large oil fire to extinguish it. What would happen and why?

(i) The fire will be put off since water extinguishes fires

(ii) The fire will spread since oil floats on water

(iii) The fire will be put off since water dissolves oil.

(iv) The fire will spread since water contains hydrogen that is a combustible gas​

Answer 1

Answer:

ii) The fire will spread since oil floats on water

Answer 2

Option ($II$): The fire will spread since oil floats on water.

Explanation:

• Because water is denser than oil, and oil's flashpoint (the temperature at which it burns) is far higher than water's boiling point.
• If you pour water upon hot oil, it will sink beneath the surface and immediately transform into a considerably bigger volume of superheated steam, and the fire will also get wider in area. It will create a hot fireball of burning oil and steam.
