Hello, why the same quantity of different elements behave in the same way (take about 22,4 L) when they are gas and they don't when they are liquid ?

scientifico said:But if a molecule is smaller won't them be more in the same volume like in this picture ?

This does not invalidate your point but the size of oxygen and nitrogen molecules is around 3 Angstroms (or 3 x 10^(-8)cm) and not half an Angstom.Nugatory said:You'd think so... Until you look at the numbers. The size of a gas molecule is something like 10-8 cm (an oxygen or nitrogen molecule is about half that size).
Elements have different states of matter (solid, liquid, or gas) based on the strength of their intermolecular forces. These forces are the attractive forces between molecules and are influenced by factors such as temperature and pressure. A high temperature and low pressure typically result in a gas state, while a low temperature and high pressure result in a solid state.
As gases, elements have high kinetic energy and are able to move freely and independently of each other. They also have low density and are highly compressible. Gases can expand to fill their container and have no definite shape or volume.
Liquids have stronger intermolecular forces than gases, resulting in a more ordered and less compressible state. They have a definite volume and take on the shape of their container. Liquids also have a higher density than gases.
The behavior of elements as gases or liquids is influenced by temperature, pressure, and intermolecular forces. Higher temperatures and lower pressures favor a gas state, while lower temperatures and higher pressures favor a solid or liquid state. Intermolecular forces play a significant role in determining the strength and behavior of elements in their different states.
Yes, elements can change between states of matter through physical processes such as melting, boiling, and condensation. These changes are driven by changes in temperature and pressure. For example, when a gas is cooled, it can condense into a liquid, and when a liquid is heated, it can vaporize into a gas.
