Concepts Of Physics MCQ Edition [Volume 2]PhysicsKinetic Theory of Gases
An ideal gas goes through the process illustrated in the figure. This process is classified as
Options
- Aadiabatic
- Bisochoric
- Cisothermal
- Disobaric
Correct answer
B. isochoric
Step-by-step solution
From the given p-T graph, the process is represented by a straight line passing through the origin. This implies that pressure is directly proportional to temperature: p T p = cT (where c is a constant) According to the ideal gas equation: pV = nRT p = ( nR V )T Comparing the two equations, we get: nR V = c Since n and R are constants for a given amount of ideal gas, the volume V must also be constant. A thermodynamic process in which the volume remains constant is called an isochoric process.
