The following graph represents the T-V curves of an ideal gas ( where T is the temperature and V the volume) at three pressures P1, P2 and P3 compared with those of Charles's law represented as dotted lines.
Then the correct relation is :
Step 1: Recall Charles’s Law
Charles’s law states that at constant pressure, the volume of an ideal gas is directly proportional to its temperature:
Step 2: Analyze the Graph
In the Temperature-Volume (T-V) graph, the slope of each curve represents:
Since pressure (P) is constant for a given curve, a steeper slope indicates a lower pressure.
Step 3: Compare the Slopes
has the least slope, indicating the highest pressure.
has the steepest slope, indicating the lowest pressure.
Step 4: Conclusion
The correct order of pressures is:
Charles’s law states that at constant pressure, the volume of an ideal gas is directly proportional to its temperature:
In the Temperature-Volume (T-V) graph, the slope of each curve represents:
Since pressure (P) is constant for a given curve, a steeper slope indicates a lower pressure.
The correct order of pressures is:
