Exothermic Process and Enthalpy:
An exothermic process is a chemical or physical change that releases energy in the form of heat. In such a process, the system loses energy to the surroundings, resulting in a decrease in the enthalpy of the system. Enthalpy (H) is a thermodynamic property that represents the heat content of a system at constant pressure. It is given by the sum of the internal energy (U) and the product of pressure (P) and volume (V).
Explanation:
When an exothermic process occurs, energy is released from the system to the surroundings. This energy is typically in the form of heat. As a result, the temperature of the system decreases because it is losing energy. This can be observed in various exothermic reactions, such as combustion reactions, where heat is given off.
The change in enthalpy (∆H) for an exothermic process is negative. This means that the enthalpy of the system decreases. Enthalpy can be thought of as the heat content of the system. When energy is released from the system, the enthalpy decreases. Therefore, option C is the correct answer.
It is important to note that an exothermic process can still result in an increase in the internal energy of the system. Internal energy is the sum of the kinetic and potential energies of the particles within the system. Even though energy is being released, the internal energy can still increase if there are other factors contributing to it, such as an increase in the kinetic energy of the particles.
In summary, an exothermic process results in a decrease in the temperature of the system and a decrease in the enthalpy of the system. The release of energy in the form of heat causes these changes.
