Which element is a noble gas?

Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Are noble gases stable?

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

What is the other name of a noble gas?

The science. The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don’t react with anything. For this reason they are also known as inert gases.

When gas is compressed what happens to the density?

By the above, we can say that when volume decreases, density increases. Therefore, when a gas is compressed its density increases.

Why do we compress gas?

Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles. When a gas is compressed, as when the scuba tank is being filled, the gas particles are forced closer together.

How does compression affect density?

When we compress air, we force those molecules closer together. The same molecules are in the air, but they occupy less space (volume) than they did when the molecules were free. As that mass of air increases, its density also increases.

What happens when a gas is compressed Brainly?

When gases are compressed, their volume decreases, and the resulting pressure increases. The temperature will change if either P or V are held constant. Since the volume decreases, then density, or m/V, increases.

What are the three physical properties of gas?

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal combustion engine provides a good example of the ease with which gases can be compressed.

What is the temperature of a gas in which the atoms are moving very very slowly?

The temperature of a gas in which the atoms are moving slowly is (THE COLD).

What happens to the molecules when a gas is compressed they maintain their temperature there is a rise in temperature there is a drop in temperature?

Since the temperature is directly related to the average kinetic energy of the gas molecules. So, the lower the volume (compression), the lower the speed of the molecules (temperature). With constant temperature, when the pressure increases, the volume drops, while if the pressure decreases the volume increases.
