**Tips to Solve Thermodynamic Relation Questions for GATE ME**

Here are the main tips to solve the Thermodynamic Relations GATE syllabus and work your way to score among the finest.

- In a cyclic process, Internal Energy remains zero overall.
- For a junction, the net heat flow is always zero.
- Internal Energy has no relation to the path of the system.
- In a system, all the internal bodies emit some form of radiation at different frequencies. And these frequencies depend on body temperature.
- In an isothermal process, system temperature is the same across the procedure.
- Adiabatic processes are those where no heat comes or goes out from a system.
- An isochoric process defines as the volume stays unchanged across the process.
- The isobaric process is where the system remains at constant pressure throughout.

**Importance of Thermodynamic Relations in GATE**
