Which has highest density solid liquid or gas?
In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them.
What is the density of oxygen at STP?
1.43 g/L The density of Oxygen is 1.43 g/L at STP.
Which has the lowest density at STP?
Helium, the noble gas with least molar mass will have the smallest density.
Which has the greater density at STP hydrogen or helium?
Therefore the density of each gas can be found by dividing the mass of one mole of the element by the volume of one mole of the gas at STP. Helium is more than 4 times more dense as compared to Hydrogen.
What is the densest heaviest element?

| Osmium in the periodic table |
Which object has the highest density lowest density Why?
This is so because if we divide each object's mass by its volume, and since all three objects have the same volume, the object with the larger mass will have the greatest density. And the object with the smaller mass, will have the lowest density.
What is the density of chlorine at STP?
The density of chlorine gas is 3.17 g/L at STP. What is the mass of 3 L of Cl2 at 800 mmHg and 250 K?
Which gas is least dense under STP?
At STP, one mole of all gas occupies 22.4 L of volume. Density is written as mass per volume. The mass of one mole of methane gas is the least among all the mentioned gases.
What is the second densest element?
Iridium appears as symbol Ir on the periodic table and has an atomic weight of 192.217 and a density of 22.56 g/cm³, making it the second-densest known element.
Which has the highest density solid liquid or gas?
In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them.
What is the density of o2 at STP?
1.43 g/L The density of Oxygen is 1.43 g/L at STP.
What is the density of methane gas at STP?
0.7168 Chemical, Physical and Thermal Properties of Methane – CH4. Phase diagram included.
| Property | Value | Value |
|---|---|---|
| Density, gas at STP; 32°F/0°C 1 atm | 44.7 | 0.7168 |
| Density, liquid at -260 °F/-162°C | 26429 | 422.6 |
| Flammable, gas and liquid | yes | |
| Flash point | 85 | -188 |
Which gas is most denser?
Actually the densest gas which has an actual use is Tungsten hexafluoride, clocking in at an astounding 13 grams per liter. Tungsten hexafluoride isn't as well known as its lighter cousin, sulfur hexafluoride, because it has a narrow range of uses.
Which has the lowest density solid liquid or gas?
Gases Bulk matter can exist in three states: gas, liquid, and solid. Gases have the lowest density of the three, are highly compressible, and fill their containers completely.
Which has higher density solid or liquid?
In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them.
What phase of matter has the lowest and highest density?
Depending on temperature (assuming constant pressure), matter can be found in solid, liquid or gas state. Matter in solid state have the highest density, with the molecules tightly packed together. Compared to other states, the kinetic energy in a solid is low.
What solid has high density?
In solids, Os has the highest density.
What is high density?
adjective. having a high concentration: entering a high-density market with a new product; high-density lipoprotein. Computers. (of a disk) having a large capacity for data storage: high-density DVDs.
What gas is the most dense?
Tungsten Hexafluoride: The densest known gas.
Which has a lower density?
Gases have a very low density because their particles are very far apart; for example, air has a density of 0.0013 g/cm3.
How do you know what has a higher density?
Density, Sinking and Floating An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float. You can really see relative densities at work when you look at a heavy object floating and a lighter one sinking.
How do you find the highest and lowest density?
This is so because if we divide each object's mass by its volume, and since all three objects have the same volume, the object with the larger mass will have the greatest density. And the object with the smaller mass, will have the lowest density.
Will a higher density be on top or bottom?
bottom Meaning that the densest (heaviest) liquid will be on the bottom of the jar and the least dense (lightest) liquid will be on top. The order of the liquids from heaviest to lightest will be syrup, glycerin, water, oil, and then alcohol will be on top.
Which has high density solid liquid or gas?
In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them. The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances between them.
