What is the characteristics of a gas?
A gas has no definite shape or volume, as it takes the shape and volume of its container. Gas particles are in constant, random motion and have weak intermolecular forces. Gases are highly compressible and tend to expand to fill the space available to them.
Why can't gases be poured?
Gases spread out to fill the available space evenly due to their high kinetic energy and lack of definite volume or shape. This makes them difficult to contain or pour like liquid or solid substances, as they tend to escape quickly into the surrounding environment.
Why do the gases in diffusion move around?
Gases in diffusion move around due to the kinetic energy of their molecules, which causes them to collide and spread out in space. This movement occurs because gas molecules are in constant random motion, and they tend to move from areas of higher concentration to areas of lower concentration in order to achieve equilibrium. Additionally, the lack of strong intermolecular forces in gases allows them to move freely and fill the available volume.
Which is a property of all gases?
One property of all gases is that they have no definite shape or volume. Gases expand to fill the container they are in, taking on the shape of that container. Additionally, gases are highly compressible and tend to diffuse and mix with each other easily.
How does the second law of thermodynamics predict the behavior of gasses?
The Second Law predicts that a reaction or process occurs if the entropy increases. Informally, "disorder" will increase; though this is not a very exact definition. Some things where this applies to in gases include:* If you bring two gases together, they will mix. * Pressures will tend to be equalized. * Temperatures will tend to be equalized.
Do gases have particles?
Not as a general rule. Charged particles tend to be chemically active unless in solution. On a dry day when the wind is blowing there tends to be a build up of charged particles which causes humans to be irritable. Static electricity is the result of a slight build up of charge whereas lightning indicates a larger build up.
Why does the s orbital fill before the p orbital?
It has a lower energy level. All else being equal, electrons tend to go into the lowest energy orbital with space available.
How do the particles of gas react in a container?
Gas particles move freely and randomly in a container, colliding with each other and the container walls. They exert pressure on the walls of the container due to these collisions. The particles have high kinetic energy and tend to fill the available space evenly.
What are the 6 characteristics of gas?
Gases have no definite shape or volume and expand to fill their container. They are highly compressible and tend to diffuse quickly. Gas particles are in constant, random motion. Gases have low densities compared to liquids and solids. They do not exhibit strong intermolecular forces. Gases are affected by changes in temperature, pressure, and volume.
Why are desert plants spaced far apart?
There is limited water available in the deserts so plants tend to space themselves to avoid competition from other plants.
Smoke and hot gases tend to go downwards?
Smoke and hot gases tend to go upwards.
What are elemets that are all unreactive gases that tend not to combine with other elements known as?
Those gases are called noble gases. They are i the 18th group of the periodic table.
