## What is the relationship between pressure and the volume of liquid?

Boyle’s Law describes the relationship between pressure and volume: The product of pressure and volume is a constant (PV=k). While Boyle’s Law refers to gases, it is significant to recall that both gases and liquids are fluids, and thus follow the same rules of behavior.

### How does pressure change with volume?

Volume and Pressure: Boyle’s Law. Decreasing the volume of a contained gas will increase its pressure, and increasing its volume will decrease its pressure. In fact, if the volume increases by a certain factor, the pressure decreases by the same factor, and vice versa.

**How do you calculate pressure in a liquid?**

Pressure due to the weight of a liquid of constant density is given by p=ρgh p = ρ g h , where p is the pressure, h is the depth of the liquid, ρ is the density of the liquid, and g is the acceleration due to gravity.

**What is the right formula of pressure?**

The formula for pressure is P = F/A, in which P is pressure, F is force, and A is area.

## Does pressure decrease with volume?

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.

### Does water pressure increase with volume?

Pressure increases with depth in a liquid because of the weight of the liquid pressing down from above. For water, pressure increases 101,325 Pa (1atm) for every 10 m of depth. As a result of this pressure increase, the water volume (ΔV/V) will decrease.

**How do you calculate liquid pressure?**

Liquid pressure is the increase in pressure at increasing depths in a liquid. This pressure increases because the liquid at lower depths has to support all of the water above it. We calculate liquid pressure using the equation liquid pressure = mass x acceleration due to g density x depth in fluid.

**What is the relationship between pressure and volume?**

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. The relationship between the volume and pressure of a given amount of gas at constant temperature was first published by the English natural philosopher Robert Boyle over 300 years ago.

## Is there a way to measure the volume of a liquid?

It is not possible to measure the volume directly, and unfortunately there is no such device as a volume sensor, however if you know the dimensions of the space filled with liquid, you can easily determine the volume.

### How does the pressure of a gas relate to the density of a liquid?

Hydrostatic pressure refers to the pressure exerted by a fluid (gas or liquid) at any point in space within that fluid, assuming that the fluid is incompressible and at rest. Pressure within a liquid depends only on the density of the liquid, the acceleration due to gravity, and the depth within the liquid.

**What is the relationship between volume and temperature?**

The relationship between the volume and temperature of a given amount of gas at constant pressure is known as Charles’s law in recognition of the French scientist and balloon flight pioneer Jacques Alexandre César Charles.
