Question

The following graph indicates the system containing 1 mole of gas involving various steps. When it moves from Z to X, the type of undergoing process is: 

 

• A. Cyclic
• B. Isothermal
• C. Isobaric
• D. Adiabatic

Hint:

In an isothermal process, the temperature remains constant, which is represented by a horizontal line on a temperature vs. volume graph.

Answer 1

The Correct Option is B

: The x-axis represents temperature (\(T\)), and the y-axis represents volume (\(V\)) of the gas.
The line from point Z to point X is a horizontal line, which indicates that the temperature remains constant during this process. In thermodynamics, when the temperature of a system remains constant, it is called an isothermal process.
In an isothermal process, the temperature does not change, and the system can either absorb or release heat to maintain that constant temperature. This is why the graph shows a horizontal line, meaning the temperature (\(T\)) remains constant (in this case, between 300K and 600K).
Thus, the correct answer is Isothermal.
