# How do you find the density of water with temperature and pressure?

## How do you find the density of water with temperature and pressure?

Density is usually denoted using the symbol ρ , so the formula for density is: ρ = m / V . It turns out that density isn’t constant for most substances, but in fact changes when external parameters change, such as the temperature or pressure.

What is the density of water at 19.5 degrees Celsius?

Fresh water has a maximum density at around 4° Celsius….Density of Water (g/cm3) at Temperatures from 0°C (liquid state) to 30.9°C by 0.1°C inc.

Temperature (°C) Volume (mL)
18.0 1.0024
19.0 1.0026
20.0 1.0028
21.0 1.0030

### What is the density of water at 19 degrees Celsius?

Density of Water (g/cm3) at Temperatures from 0°C (liquid state) to 30.9°C by 0.1°C inc.

Temperature (°C) Volume (mL)
18.0 1.0024
19.0 1.0026
20.0 1.0028

What is less dense than water?

Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.

#### What makes water dense?

Adding salt to water makes the water denser. As the salt dissolves in the water, it adds mass (more weight to the water). This makes the water denser and thus allows more objects to float on the surface that would sink in fresh water.

What is the density of water in imperial units?

In imperial units, the density of water is 1.94 slugs/ft^3, and multiplying by 32.2 ft/s^2 results in 62.4 lb/ft^3. This calculation is not used, however, when density is measured in lbm.

## What is the unit weight of water?

Scientists and engineers use two main measurement systems to define the unit weight of water. In the metric, or SI, system the unit weight of water is 998 kg per cubic meter — kg/m3 — or approximately 1 g per cubic centimeter, g/cm3. In imperial measurements, the unit weight of water is commonly given as 62.4 pounds per cubic foot, lbs/ft3.
