## What is the relationship between pressure and volume on a graph?

Table of Contents

Figure 9.14 The relationship between pressure and volume is inversely proportional. (a) The graph of P vs. V is a hyperbola, whereas (b) the graph of ( 1 P ) vs. V is linear.

## What is the graph of pressure against volume?

Graph of Pressure (P) Versus Volume (V): Each curve is rectangular hyperbola and corresponds to a different constant temperature and is known as an isotherm (constant temperature plot). Higher curves correspond to higher temperatures. It should be noted that volume of the gas doubles if pressure is halved.

**What’s the relationship between pressure and volume?**

The Relationship between Pressure and Volume: Boyle’s Law As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart.

### What is the shape of the pressure vs 1 volume graph?

A plot of pressure versus volume shows that as volume increases, pressure decreases (and vice versa), indicating an inverse relationship. Graphing 1/pressure versus volume generates a straight line, which is also indicative of an inverse relationship between the two variables.

### What is the difference between pressure and volume?

When a gas occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure (assuming the amount of gas and the temperature do not change). Since P and V are inversely proportional, a graph of 1/P vs. V is linear.

**Why is the pressure vs volume graph not linear?**

The harder you squeeze (the more pressure you apply) the smaller the resulting volume will be. Imagine a bicycle pump compressing air into a tire. 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.

#### What is pressure short answer?

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.
