Why is pressure vs volume graph not linear?

Because there is so much empty space between gas molecules, it is easy to see why a gas is so compressible. As pressure is applied to the pump, the same number of gas molecules are squeezed into a smaller volume. The dependence of volume on pressure is not linear.

Why is P or 1 VA straight?

Since mols n , the universal gas constant R , and T are held fixed intentionally, if we chose to make a graph of P vs. 1V , it is linear. That’s a mathematical result of forcing nRT to be a constant.

Why is pressure and volume graph curved?

The pressure and the volume here are inversely proportional to each other. As pressure increases, the volume will decrease. As pressure decreases, the volume will increase. The graph of Boyle’s law is called the PV curve.

Should a plot of V as a function of P yield a straight line?

By plotting V versus 1/P (or P versus 1/V), we obtain a straight line with slope = const. Therefore, a gas is ideal when the plot of V versus 1/P (or P versus 1/V) yields a straight line.

Is pressure volume linear?

Since P and V are inversely proportional, a graph of 1/P vs. V is linear. Figure 6. The relationship between pressure and volume is inversely proportional.

Is pressure vs volume linear?

Since P and V are inversely proportional, a graph of 1 P vs. V is linear. with k being a constant. Graphically, this relationship is shown by the straight line that results when plotting the inverse of the pressure ( 1 P ) versus the volume (V), or the inverse of volume ( 1 V ) versus the pressure (P).

What does this graph indicate about the relationship between P and 1 V?

The graph of V against 1p is a straight line through the origin. This means that the measured volume is inversely proportional to the pressure — Boyle’s Law.

What type of graph would you get when p is plotted against 1 V at constant temperature?

The graph between PV vs P at constant temperature is linear parallel to the pressure axis.

Why is PV against PA straight line?

Since temperature is kept constant the RHS of the equation is a constant. As such the graph of PV against P should be a straight line parallel to the P axis.

What graph would you plot against pressure which would give a straight line?

What does the area under the pressure versus volume graph represent?

In our experiment, pressure and volume data were collected and plotted on a pressure versus volume graph. The area under the curve is the work done by the force provided by gravity and the weights on the piston. Work was done on the gas, which is positive.

Why is my air pressure graph curved?

Compared to the link I posted, your axes are swapped, but nevermind. It describes the exponential decay of atmospheric pressure with increasing altitude. As exponential functions are curved (in a linear axis scaling as yours), your graph is not a streight line. The physics behind this comes from the fact, that air is a compressible gas.

How do you find the area under a pressure curve?

Since the graph of pressure versus volume is not a linear relationship, the area under the curve is most accurately determined using integral calculus. To avoid having to get the equation for the curve and integrating it between two points along the x-axis, we will choose a section of the graph that is as close to a straight line as possible.

What happens to pressure as volume decreases in a gas?

We can see from the graph (looking from right to left) that when the volume of the gas decreases, the pressure increases. As the volume of the gas approaches very large volumes, the pressure trends to 0 pascals. At the other end of the graph, we see that if the volume drops towards zero, the pressure trends towards infinity.
