Solution

The correct option is D All of the above
Bringing the temperature below the ignition point ensures that no combustion-related hazard occurs as the fuel cannot catch fire below the ignition point. Water forms a layer and removes air(oxygen) from the fire triangle by acting as an insulator of air.

Q. The air temperature above coastal areas is profoundly influenced by the large specific heat of water. One reason is that the energy released when 1m3 of water cools by 1∘C will raise the temperature of a much larger volume of air by 1∘C. Find this volume of air. The specific heat of air is approximately 1kJ/kg∘C. Take the density of air to be 1.3kg/m3.
Q. Assertion :The density of water remains constant as it is cooled from room temperature until its temperature reaches 4oC Reason: Below 4oC,the density increases.
