The curve which represents the isothermal process is called:
Correct answer: A. Isotherm
- A. Isotherm
- B. Both "A" and "C"
- C. Adiabatic
- D. Either "A" or "C"
Explanation
An isothermal process is a thermodynamic process that occurs at a constant temperature. In such a process, the temperature of the system remains unchanged as it undergoes changes in pressure and volume. This is typically represented by a horizontal line on a pressure-volume graph. The term "isothermal" itself indicates that the temperature remains constant throughout the process.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
