FAQs on Relation Between Enthalpy & Internal Energy Video Lecture - Basic Physics for IIT JAM
| 1. What is the difference between enthalpy and internal energy? |  |
Ans. Enthalpy is a thermodynamic property that accounts for the heat flow in a system, while internal energy refers to the total energy stored within a system. Enthalpy includes both the internal energy and the energy associated with the system's volume and pressure.
| 2. How are enthalpy and internal energy related? | |
Ans. Enthalpy and internal energy are related through the equation: Enthalpy = Internal Energy + Pressure x Volume. This equation shows that enthalpy is the sum of the internal energy and the product of pressure and volume.
| 3. Why is enthalpy a useful property in thermodynamics? | |
Ans. Enthalpy is a useful property in thermodynamics because it allows us to measure and analyze energy changes during processes that occur at constant pressure. It provides insights into heat transfer and work done in a system, making it convenient for practical applications and engineering calculations.
| 4. How does the enthalpy change during a chemical reaction? | |
Ans. The enthalpy change during a chemical reaction is known as the heat of reaction or the enthalpy of reaction. It is determined by the difference in enthalpy between the products and the reactants. If the enthalpy of the products is higher than that of the reactants, the reaction is exothermic, releasing heat. Conversely, if the enthalpy of the products is lower, the reaction is endothermic, absorbing heat.
| 5. Can enthalpy and internal energy be negative? | |
Ans. Yes, both enthalpy and internal energy can be negative. Negative values indicate a decrease in energy. For example, a negative enthalpy change in a reaction represents an exothermic process where energy is released. Similarly, a negative internal energy indicates a decrease in the total energy content of the system.
