sports scuba diving# Why does the pressure decrease as volume is increased at a constant temperature?

Last Updated: 10th May, 2020

**pressure increases**, then

**volume decreases**and vice versa, when

**temperature**is held

**constant**.” When

**pressure increases**, the same number of molecules, or matter, are being forced closer together to occupy a shrinking space, their

**volume decreasing**while their density correspondingly

**increases**.

Then, what will happen to the volume as temperature is increased at a constant pressure?

Decreasing **Pressure** The combined gas law states that the **pressure** of a gas is inversely related to the **volume** and directly related to the **temperature**. If **temperature** is held **constant**, the equation is reduced to Boyle's law. Therefore, if you decrease the **pressure** of a fixed amount of gas, its **volume will increase**.

Beside above, why does temperature decrease when volume increases? 1) If the **volume** of a container is **increased**, the **temperature increases**. 2) If the **volume** of a container is decreased, the **temperature decreases**. This means gas molecules will move faster and they will impact the container walls more often.

Thereof, why does pressure decrease as volume increases?

Because the **volume** has **decreased**, the particles will collide more frequently with the walls of the container. More collisions mean more force, so the **pressure** will **increase**. When the **volume decreases**, the **pressure increases**. This shows that the **pressure** of a gas is inversely proportional to its **volume**.

How will the pressure change if the temperature is doubled keeping the volume constant?

1. **If the temperature is doubled** and the **volume** is kept **constant** then the **pressure would** also double because **temperature** and **pressure are** interlinked. The Brainliest Answer! so **pressure** becomes double **when volume** gets halved..
