The questions based on the given figures are to be stated. Concept introduction: Exothermic process is a thermodynamic process in which energy is released on the completion of the process. Energy released either in the form of heat, light, sound or any other form. Enthalpy change ( Δ H ) is also a thermodynamic phenomenon which represents simply the energy change during the process. This enthalpy change may be positive, negative or zero. If heat is evolved from the system then the enthalpy change is negative and the process is known as exothermic. If heat is supplied to the system then the enthalpy change is positive and the process is known as endothermic. If energy change is zero then neither the process is exothermic nor the endothermic. Condensation is a phenomenon is which gaseous form of matter converts directly to the liquid and vice versa. To determine: The exothermic processes from the process given in figure P5 .8 .
