exothermicity मीनिंग इन हिंदी

Sodium tungstate can also be produced by treating tungsten carbide with a mixture of sodium nitrate and sodium hydroxide in a fusion process which overcomes the high exothermicity of the reaction involved.
Fuels are chosen on the basis of the exothermicity of their oxidation, ranging from powdered metals, such as aluminium or magnesium, to organic materials, possibly with a self-contained partial oxidant.
When sufficient material is present in the feed to sustain the process temperature solely by exothermic reaction ( i . e . without the addition of fuel or electrical heat ), the process is said to be " autogenous . " Processing of some sulfide ores exploit the exothermicity of their combustion
