## FAQs on Thermodynamic Processes Video Lecture - Physics Class 11 - NEET

 1. What are thermodynamic processes?
Ans. Thermodynamic processes are a series of changes that occur in a system, involving the transfer of energy as heat and work. These processes can be classified into various types, such as isothermal, adiabatic, isobaric, and isochoric, each characterized by specific properties and equations.
 2. What is an isothermal process?
Ans. An isothermal process is a thermodynamic process in which the temperature of the system remains constant throughout the entire process. This means that the heat transfer into or out of the system is balanced by the work done on or by the system, resulting in no change in internal energy.
 3. How does an adiabatic process differ from an isothermal process?
Ans. An adiabatic process is a thermodynamic process in which there is no heat transfer into or out of the system. Unlike an isothermal process, the temperature of the system changes during an adiabatic process due to the work done on or by the system. Adiabatic processes are characterized by changes in the internal energy of the system.
 4. What is the significance of the first law of thermodynamics in thermodynamic processes?
Ans. The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, but can only change its form. In the context of thermodynamic processes, this law is crucial as it helps determine the transfer of heat and work, allowing us to analyze and understand the energy changes occurring in a system.
 5. How can thermodynamic processes be applied in real-life situations?
Ans. Thermodynamic processes find practical applications in various fields. For example, in an automobile engine, the combustion process is an example of an adiabatic process, where the expansion of hot gases does work on the piston. In refrigeration systems, the compression and expansion of gases involve isentropic processes. Understanding thermodynamic processes is essential for optimizing energy efficiency and designing systems with minimal heat loss or maximum work output.
