Question

An ideal gas undergoes the process a→b→c→a shown in the pV diagram. In the figure, Pa Pc = 240 kPa, Vb Vc = 40 L, Va = 15 L, and Pb = 400 kPa. How much heat is gained by the gas in this a→b→c→a process?

The image shows a pressure-volume (p-V) diagram, which is commonly used in thermodynamics to illustrate changes in pressure and volume of a gas in a closed system. 

In the diagram, there are three points labeled as a, b, and c. These points are connected sequentially by arrows, forming a closed triangular path.

- The line segment from point a to point b is slanted upwards, indicating an increase in both pressure and volume.
- The line segment from point b to point c is vertical, showing a decrease in pressure at constant volume.
- The line segment from point c back to point a is horizontal, representing a decrease in volume at constant pressure.

This path can represent a thermodynamic cycle, where the system returns to its initial state after going through the processes represented by the segments. Each segment corresponds to a specific thermodynamic process, such as isobaric (constant pressure), isochoric (constant volume), or isothermal (constant temperature) processes.
