There are many forms of the heat changes accompanying the chemical reactions like Standard heat of combustion and Standard heat of formation , Combustion is the fast combination between the substance and oxygen .
The calculation of the change in heat content is of a great importance where , the calculation of the change in heat content accompanying the burning of different fuels , helps us during designing...
Exothermic and Endothermic reactions When heat transfers from the system to the surrounding , the internal energy of the system decreases and this process is called Exothermic process , When heat transfers from the...
Each substance stores an amount of energy inside it , This amount of energy called the internal energy , This amount of energy is the summation of three types of energy which are the...
