density of water at various temperatures

by Cassidy Boyer Published 4 years ago Updated 3 years ago

Water facts

  • Density of pure water is a constant at a certain temperature not depending on sample.
  • The density of water varies according to temperature and the degree of purity.
  • At 4 degrees Celsius pure water has a density of 1g/mL or 1kg/L and a specific gravity of 1.
  • Freezing water expands over 9% by volume and ice floats on water because it is lighter.

What temperature is the highest density of water?

State the Reason. Density of water is the highest at 40C. Above 40C, the water molecules can not come closer due to thermal motion. Below this temperature, water molecules get arranged via formation of more and more hydrogen bonds and they cannot come closer. So, liquid water has higher density than ice.

Do different temperatures affect water density?

Temperature Affects Density. The density of water can also be affected by temperature. When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. This is represented by the increase in the size of the box from Fig. 2.2 A to 2.2 C.

Does the density of water depend on its temperature?

Water does not have an absolute density as its density varies with temperature. It has a higher density in the liquid state than the solid. Check the Density Vs Temperature graph given below to understand how density changes with temperature.

At what temperature is water density highest?

Pure water has its highest density 1000 kg/m3 or 1.940 slug/ft3 at temperature 4°C (=39.2°F).

At what temperature does water density decrease?

Water has maximum volume at 4-degree Celsius and maximum density at 4-degree Celsius. But when water is cooled down further its volume starts increasing and hence, the density of water decreases when cooled further below than 4-degree celsius.

What is the density of water at 20.2 degrees Celsius?

998.23 kg/m^3In general, we say that the density of water is 1000 kg/m^3 (or 1 g/cm^3). But you're right that it does vary a little bit with temperature. It is exactly 1000 kg/m^3 at 4 degrees Celsius. At 20 degrees Celsius it is 998.23 kg/m^3 ( or 0.99823 g/cm^3).22-Oct-2007

Water Density

If you're still in school, you've probably heard this statement in your science class: " Density is the mass per unit volume of a substance". On Earth, you can assume mass is the same as weight, if that makes it easier.

Water's density varies with temperature

Growing up with an older brother was difficult, especially when he had his friends over, for their favorite activity was thinking of ways to antagonize me. I was able to use water density once to at least play a trick on them, though. One hot summer day they climbed the huge hill next to our house to dig a hole to hide their bottle-cap collection.

Ice is less dense than water

If you look at this picture you can see that some of the iceberg is below the water level. This is not a surprise, but actually almost all of the volume of an iceberg is below the water line, not above it. This is due to ice's density being less than liquid water's density. Upon freezing, the density of ice decreases by about 9 percent.

We said ice floats on water, but what about "heavy ice"?

We already said ice floats on water because it is less dense, but ice of a special kind can be denser than normal water. "Heavy ice" is 10.6 percent denser than normal water because the ice is made from "heavy water".

What is the formula for water density?

With respect to the definition, the density formula is represented as Density (ρ) = Mass (m)/Volume (V).

Why does ice float on the surface of the ocean?

When temperature is further cooled down to the freezing point, water solidifies and expands, resulting in low density. This is the reason why ice blocks (less dense than water) floats on the surface of the ocean water. As water freezes to its solid form of ice, the density is reduced to about 9 percent.

Is the density of water higher in solid form or liquid form?

In general, the density of a matter is higher in solid form, as compared to the density of the same matter in liquid form. The density of water is both directly or indirectly proportional to temperature. To be more precise, water density is higher in colder temperatures, until a certain limit. It is found to be highest when ...

Does pressure play a role in water density?

Of course, pressure does play a role in the subject of water denseness.

Is water at the bottom of the ocean more dense?

As we go deeper, the water temperature gradually decreases. Consequently, water at the sea/ocean bottom is more dense, as compared to the one at surface. For your reference, the table for water density at varied temperatures is given below. Density of Water. Temperature (° C)

Is water the most abundant substance on earth?

This article provides information regarding density of water at different temperatures, including the density value at room temperature. Water is undoubtedly the most abundantly found chemical substance on earth.

Does salt float over water?

In short, density of water is directly proportional to salinity. Thus, water with lower salt content will float over water with higher salt concentration.

What is the density of water?

The density of water is approximately 1g/m3 (1 gram per cubic centimeter) or 62 Ib/cu ft (pounds per cubic feet) or 1000 kg/m3 (kilograms per cubic meter) at a temperature of 4°C (39.2 °F), which can also be referred to water density at standard temperature and pressure (STP).

Why is water density taken as 1?

Water density has been taken as 1, as water was used as a standard of measuring the metric unit of mass of other liquids which are measured. Liquids/objects with a density with a density lower than the water density will float when placed in water and objects with a higher density will sink. The equation for density is defined below:

What is the position of a hydrometer?

The hydrometer, is put into a cylinder filled up with the liquid to be tested. The position at which the liquid touches the stem of the hydrometer is the relative density of the liquid (measured against a density of water of 1.0). Hydrometer float lower in less dense liquids and float higher in dense liquids, as water is used as a standard measure ...

What is the density of water in a hydrometer?

Hydrometer float lower in less dense liquids and float higher in dense liquids, as water is used as a standard measure with a water density of 1.0. Hydrometers are common in the alcohol industry for measuring the levels of alcohol in spirits or sugar in liquids. The density of water against Temperature (°C)

What is the method used to measure the density of a liquid?

Measuring Density of liquid using Hydrometer. A hydrometer is a laboratory measuring device, which is a glass apparatus and measures the density of a liquid. The measuring apparatus is similar to a thermometer with a weighted bulb (usually mercury) at the bottom to make it sit upright.

Why do we see icebergs floating in water?

This is why we see icebergs and ice floating in water as they are approximately 9% less dense than water. This is an important when considering the local ecosystem in lakes and rivers. The top layer of a lake begins colder and ice starts to form on the surface.

Does temperature affect water density?

Does temperature and pressure affect water density? Water comprises of hydrogen and oxygen atoms, with a chemical formula of H 2 O and is a unique molecule as water density is affected by temperature when the pressure is constant.

How does this water density calculator work?

This is a tool that helps you determine water density in kg/m 3 in two different situations. The first is based only on temperature values and in this case you only need to input temperature in Celsius, Fahrenheit, Kelvin or Rankine.

Example calculation

Let’s take for example a sample of water at a temperature of 15 degrees Celsius with a salinity of 3000 mg/L.
