During the isothermal process, the temperature:
Correct answer: B. Remains constant throughout the process
- A. Remains constant during the initial phase of the process
- B. Remains constant throughout the process
- C. Alters throughout the process
- D. Increases throughout the process
Explanation
In an isothermal process, the temperature of the system remains constant. For an ideal gas, this means that any heat added to the system is used to do work, rather than changing the internal energy.

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.
