How many kg is 1m3 of water?
kg is the unit of mass. So to convert to kg, you should know the density of the matter with which you have filled the volume. for example, density of water is 1000 kg/m3. hence, mass of 1m3 of water= 1000kg/ m3 X m3= 1000kg. density of air is approximately 1.225 kg/m3. hence, mass of 1m3 of air=1.225kg/ m3 X m3= 1.225kg.
How do you calculate density of water?
Calculate the density by dividing the mass by the volume. Using the equation density = mass/volume, you can determine the density of water. Plug in the values of mass and volume you determined and solve. Mass of the water: 7.3 g. Volume of the water: 7.3 mL. Density of water = 7.3/7.3 = 1 g/mL.
How to calculate the density of water?
What are the 3 formulas for density?
- To work out density: p = m / V.
- To work out the mass: m = p x V.
- To work out the volume: V = m / p.
What is the maximum density of water?
Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1g/cm3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less then 1 g/cm3.

Why is the density of water maximum at 277 K?
Above 277K: Expansion factor (due to increase in thermal energy) becomes greater than the contraction effect (caused by breaking of hydrogen bonds), naturally, volume increases and the density decreases. Thus, the density of water is maximum at 277 K.
What is maximum density of water?
The maximum density of water is at 4°C as there are two opposite effects that are in balance. The density of ice is less than liquid water, so it floats. Upon freezing, the ice density decreases by about 9%.
What is the volume of water?
To find the capacity of a rectangular or square tank: Multiply length (L) by width (W) to get area (A). Multiply area by height (H) to get volume (V). Multiply volume by 7.48 gallons per cubic foot to get capacity (C).
What is viscosity of water?
The viscosity of water at a temperature of 20 degrees Celsius is approximately 0.01 poise or 10-3 Pa. s (Pascal seconds). Viscosity is a measure of the resistance of a fluid to deformation at a given rate.
Why do ice float on water?
Believe it or not, ice is actually about 9% less dense than water. Since the water is heavier, it displaces the lighter ice, causing the ice to float to the top.
Is a Litre of water 1 kg?
1 kilogram of pure water equals 1 liter when reaching its maximum density of 1 kg/l, at the temperature of 39.2 °F or 4 °C.
What is the density of 1 liter of water?
1 kg /LWater has a density of 1 kg /L, that is, 1 liter of water has a mass of exactly 1 kg.
Why is water so heavy?
Not only because there is more water, but because more molecules are being packed tighter together to form a much denser substance. The density of water is 1 gram per cubic centimetre. This is a variable which can change depending on temperature, largely as water either heats up or freezes.
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 density of water?
Density is the mass per unit volume of a substance. The density of water is most given as 1 g/cm3, but below is the density of water with different units. It's no coincidence that water has a density of 1. Density is mass divided by volume (ρ=m/v), and water was used as the basis for establishing the metric unit of mass, ...
How to find the density of a liquid?
Calculating the Density of a Liquid With a Hydrometer. If you're trying to calculate the density of a liquid, you also can do so by using an instrument known as a hydrometer. A hydrometer looks like a thermometer with a large bulb at one end to make it float.
How to measure density of a substance?
In order to measure the density of a substance, you can calculate a regularly-shaped object's volume and proceed from there, measure the volume of a liquid or how much liquid an irregular object displaces in a graduated cylinder, or use a hydrometer to measure the density of a liquid.
How to find the volume of an object?
If the object has an irregular shape and you can't easily calculate its volume, you can find its volume by placing it in a graduated cylinder filled with water and measuring the volume of water it displaces. Archimedes' Principle states that an object displaces a volume of liquid equal to its own volume.
Does water change density?
Water's density changes depending on the temperature, so if you're doing an experiment close to or past water's boiling or freezing point, you'll need to use a different value to take into account the change in density. Both steam and ice are less dense than water.
Is salt water higher than sea water?
Saltwater (like the oceans) has a different density which depends on how much salt is dissolved in the water. Seawater density is typically slightly higher than the density of pure water, about 1.02g/cm 3 to 1.03g/cm 3.
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.
Water facts
Density of pure water is a constant at a certain temperature not depending on sample.
What is the specific weight of water?
The specific weight is the weight per unit volume of a material. The specific weight of water is 9.81 kN/m3 or 62.43 Ib/ft3 . The specific weight is defined by the equation below:
When does the density of water decrease?
As the temperature increases, the density decreases. However, it should be noted that below 4°C, the density of water decreases when the temperature goes below zero. The table below indicates that when the temperature decreases below 4°C, the density of water decreases. When the temperature increases to 100°C, the density decreases as well.
Why does water float on water?
When water reaches a temperature below 0°C, the water turns to ice, and is less dense than water causing it to float on water. This is due to the decrease in density and this is attributed to atomic formation of ice. Temperature (°F)
What is the maximum density of water?
The maximum density of water occurs around 4° Celsius. The density of ice is less than liquid water, so it floats. Upon freezing, the ice density decreases by about 9%.
How to find the density of water?
We will need a tall glass cup, honey, water, coconut oil and food colouring, Step 1: Pour a one-quarter cup of honey, Step 2: Pour a one-quarter cup of coloured water gently on top of the honey. Step 3: pour a one-quarter cup of coconut oil on top of the coloured water.
What is density in science?
The density of a material is defined as its mass per unit volume. It’s a measurement of how tightly matter is packed together. The density of a substance can be explained as the relationship between the mass of the substance and volume it takes up. It is the weight of the water per its unit volume, which depends on the temperature of the water.
Does water have an absolute density?
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.
Is water temperature dependent?
It is temperature- dependent, but this relation is said to be non- linear and also it is unimodal in nature rather than monotonic. When it is cooled from the room temperature, the liquid water tends to become increasingly dense, as with another kind of substances, but approximately at about 4°C, pure water is said to reach its maximum density.
