Which liquid has the highest density? Why?

Stay tuned to Byju's for further information on other subjects such as mercury density. In the meantime, here are some of your questions answered:

Water is used because it is abundant and easy to work with. Mercury has a density of 1090 kg/m3 so it can be used as a benchmark for other elements.

The most important property of any element is its density. All other properties can be derived from this one number. For example, the volume of an object can be calculated by multiplying its mass by its density, while the amount of substance in a quantity of material can be determined using the formula weight in milligrams multiplied by density in grams per milligram.

You might wonder why we need to know element density. The short answer is that all other properties can be derived from this single number.

Density also has important implications for us humans.

Is water the densest thing?

Water is the densest at 39 degrees Fahrenheit (or 3.98 degrees Celsius). This is due to the fact that the molecules are closest together at this temperature. The molecules get heavier as they get closer together. The lighter the molecules are, the farther apart they are. This means that there are more empty space between them.

Liquids such as oil and water have a similar structure except that they contain a large number of hydrogens attached to each oxygen or nitrogen atom. This makes liquids very reactive because any chemical reaction requires a pair of atoms to join together to form a new molecule. Since all molecules need to be separated from one another for this process to take place, all liquids are potentially flammable.

The more hydrogen atoms you have attached to an atom, the less dense it is. Denser objects are more difficult to burn than gases which are mostly empty space. Water is twice as dense as air which is why it's so difficult to burn. Fire needs oxygen to burn and liquids do not support combustion because there are no free radicals created when burning a liquid, only gasses. Even if you put all the oxygen in the world into a bottle of alcohol, it would still go out.

Oceans cover 71 percent of the earth's surface and weigh in at about 1.5 billion tons. That's more than all the other planets combined!

What is the most dense liquid on Earth?

Mercury - 480 kg/m3 mercury vapour, 517 kg/m3 liquid mercury

Earth's liquids are mostly water (78%) with some oil (15%), natural gas (4%) and less than 1% of other liquids. The remaining 1% is made up of solid bodies such as ice caps or deep underground. Oil and natural gas are both gases under high pressure so they can be forced out of sand or rock where they are stored.

Liquids don't normally form at temperatures below 0 Celsius but some substances become liquids at very low temperatures. For example, hydrogen becomes a liquid at -252 degrees Celsius while helium remains a gas even at room temperature.

The world's lowest temperature observable by humans is -89.2 degrees Fahrenheit or -32 degrees Celcius. This was recorded in Russia in 1990 during an experiment to see how long copper wires could be kept viable by freezing them.

The idea of testing metals at extreme cold conditions came from concerns about nuclear weapons proliferation. Nuclear explosions heat metal surfaces to many hundreds of degrees Celsius for several seconds which helps determine their strength.

Which of these solids has the highest density?

What is the world's highest dense solid?

  • Rhenium, 21.2 g/cc.
  • Uranium, 20.2 g/cc.

Which substance is more dense?

The solid (steel) has the highest density, the gas (air) has the lowest density, and the liquid (water) has a density that falls somewhere in the middle... density.

Why is water the densest at 39 degrees?

This is due to the fact that water's molecular structure and hydrogen bonding take up more space when it is frozen solid than when it is a warmer liquid. In other words, even though the water is hardening into ice, the molecules are more apart. This makes them less likely to interact with each other and create more empty space.

At 0 degrees Fahrenheit, or -17.8 degrees Celsius, all of the water is frozen out and only H2O remains. The molecules are too far away from each other to create any internal space so there is no room for anything else inside the cell.

As temperature increases beyond 0 degrees, the ice starts to melt, increasing the size of the water molecule. This makes it easier for other substances to enter the cell through its membrane. As more and more molecules enter the cell, there is now room for something else to fill up the space - like your hand in freezing water! At 32 degrees F (0 degrees C), half of the water is frozen out and half is liquid, but the ratio is almost exactly equal. The density of water is not changed by this transformation from ice to liquid.

As you increase the temperature further, more and more ice melts until at 100 degrees F (38 degrees C) there is only H2O left. Density is reduced as water turns into a gas. At this point the cell can float up in the water.

Which has the greatest density at STP?

STP stands for Standard Temperature and Pressure, and the volume of 1 mole of gas at STP is 22.4 litres. Because volume is constant, density is proportional to mass. Copper has the largest molar mass of the elements listed. As a result, the element with the highest density at STP is copper. Silicon has the lowest molar mass, so it is the lightest element at STP.

Density increases as you go up the column on the periodic table because molecules get bigger and occupy more space. At standard temperature and pressure, carbon dioxide molecules are smaller than hydrogen molecules, so they pack more tightly into the same amount of space. Denser gases like argon and krypton have similar sizes of atoms, so their densities increase as you move up the column as well.

At room temperature, the average molecule of CO2 is surrounded by eight other molecules, but at 100 degrees Celsius only two molecules stand out from a sea of air. The molecules in a dense gas do not spread out far enough to touch each other, which means that there is a lot of space between them. A full gallon of CO2 at one atmosphere pressure (101.3 kg/m2) would be 14.5 metres high. At this distance, even a small object like a person could not penetrate the cloud layer.

A cubic meter of air at one atmosphere pressure contains about 2.7 million molecules.
