why do we take special care to store kerosene while wood can be stored eculy?
Answers
Explanation:
Care needs to be taken while storing kerosene as if it is exposed to air, it may ignite with it and catch fire. Ignition temperature of kerosene and petrol is low so it can catch fire more easily.
hope it will help u ✌️✌️
Explanation:
Why is more care needed to store kerosene than coal, though both are fuels in short?

Kerosene is a liquid, whose components are notably lighter than water and evaporate at ambient temperature and mix with air. That mixture can be flammable at some point, so you need to take special measures, such as ventilation or closure of the deposit, to avoid the issue of a fire or a detonation.
On the other hand, coal is a solid fuel. It contains volatile compounds that are released during combustion, but normally the amount at ambient temperature is small. Domestic applications use anthracite, a kind of coal that is very dry, with a total volatile content (released at 650 ºC) lower than 15 %. It is perfectly safe to handle at ambient temperature without any preventive measure, and this is one of the reasons of its use in small, domestic heaters.
However, other coals, such as high-volatile bituminous, sub-bituminous or lignite can have up to 60 % volatile matter (at 650 ºC) and DO need indeed special measures when stored at ambient temperature. Fires are very common in open coal yards, and special care has to be taken when stored in closed coal hoppers and preheated for drying in coal mills. The situation can be worse with peat and biomass, whose volatile contents are higher, but only when dried, because their humidity contents are much higher, and this logically prevents this kind of incidents.
