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.

How do you calculate density of water?
The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter.
How do I calculate density?
The formula for density is the mass of an object divided by its volume. In equation form, that's d = m/v , where d is the density, m is the mass and v is the volume of the object.
What is the density of water?

What is the density of water at 4c?
1.0 g c m − 3Answer: Solution: The density of water at 4°C is 1.0 g c m − 3 g\ cm^{-3} g cm−3.
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.
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.
Why does ice float on top of water?
Once you get below water's freezing point (3 2°F/0°C), the density of water decreases because ice is less dense than water. This is why ice floats on top of water and, when you put ice cubes in a glass of water, they don't just sink straight to the bottom. The chart also shows that, for the range of temperatures typical for indoor science labs ...
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.
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".

How many hydrogen atoms are in water?
A water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice, and gaseous state, steam (water vapor). Water covers 71% of the Earth's surface. It is vital for all known forms of life.
Why is water important to life?
Water plays an important role in the world economy as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. Approximately 70% of the fresh water used by humans goes to agriculture.
