**Is pressure and volume directly proportional?**In

**byebyebimari**

For a fixed mass of an ideal gas kept at a fixed temperature, **pressure and volume** are **inversely proportional**. Or Boyle’s law is a gas law, stating that the **pressure and volume** of a gas have an inverse relationship. If **volume** increases, then **pressure** decreases and vice versa, when temperature is held constant.

Also question is, why is pressure inversely proportional to volume?

Boyle’s Law is a relationship between **pressure** and **volume**. In this relationship, **pressure** and **volume** have an **inverse** relationship when temperature is held constant. If there is a decrease in the **volume** there is less space for molecules to move and therefore they collide more often, increasing the **pressure**.

Subsequently, question is, what is the mathematical relationship between pressure p and volume V )? K is a constant? 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**).

In this way, how does pressure affect 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.

Why are temperature and volume directly proportional?

If **temperature** and pressure are kept constant, then the **volume** of the gas is **directly proportional** to the number of molecules of gas. If the **temperature and volume** remain constant, then the pressure of the gas changes is **directly proportional** to the number of molecules of gas present.
