Logarithm of readings of pressure and volume for an ideal monoatomic gas
were plotted on a graph as shown in figure. By measuring the gradient, we can conclude that process is:
Options:
Answer:
D
Solution:
From the graph, the magnitude of the slope of log P against log V is 1.4.
A monatomic ideal gas has γ = 5/3, not 1.4, so this is not its adiabatic path.
The slope is neither 0 (isobaric) nor -1 (isothermal). Answer D.
