Why is the volume on the x-axis?

It really all comes down to which variable you’re changing and which one you’re measuring. I think more often, pressure will be measured against volume, so volume would then be in the x -axis.

Does pressure or volume go on the x-axis?

We can graph pressure vs volume, with pressure on the y-axis and volume on the x-axis.

What is the difference between the X and y-axis on a graph?

A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis.

What does a curve represents on a PV diagram?

The product of pressure and volume is represented by an area on a p-V diagram. The area under the curve on a p-V diagram tells us the work done during the process. This can be found by adding up the areas of lots of thin rectangles, each of which corresponds to a constant (or very nearly constant) pressure.

Why is volume the independent variable and pressure the dependent variable?

Explanation: If you manipulated (changed) the pressure and measured the volume as a result, the pressure would be the independent variable and the volume would be the dependent variable because the volume was dependent on the pressure.

What would be plotted on the X axis and the y-axis if pressure is the dependent variable?

In graphing jargon, the independent variable is plotted on the x-axis and the dependent variable is plotted on the y-axis. In any data set, the independent or X-variable is the one that was chosen or manipulated by the experimenter.

What would be plotted on the X axis and the y axis if pressure is the dependent variable?

Why does the area under PV diagram indicate in thermodynamics process?

It is useful to plot the changes in the state of a gas during a thermodynamic process. As described on the work slide, the area under a process curve on a p-V diagram is equal to the work performed by a gas during the process. On the right of the figure we have plotted the temperature versus the entropy of the gas.

Why is volume a dependent variable?

What does the graph infer about the relationship of volume and pressure at constant temperature?

The relationship between pressure and volume is inversely proportional. (a) The graph of P vs. It is summarized in the statement now known as Boyle’s law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured.
