Consider the \((P\text-V)\) diagram for an ideal gas shown in the figure.
Out of the following diagrams, which figure represents the \((T\text-P)\) diagram?
1.
2.
3.
4.
3. Hint: The pressure is decreasing.
Step 1: Find the graph corresponding to the given graph.
Given, PV = constant. Hence, we can say that the gas is going through an isothermal process. Clearly, between states 1 and 2, the temperature is constant and the gas expands and the pressure decreases i.e. which corresponds to diagram(iii).
