Gases do not have definite?
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.
What source of heat is compression?
The three variables are P, V and T. n doesn't change. R is a constant. If gases were perfectly compressible, the volume would decrease inversely proportional to the increase in pressure. There would be no reason for the temperature to increase. But gases are not perfectly compressible. V does not decrease linearly with increases in P. In order to keep the Ideal Gas Law in balance, T has to increase. or Because the molecules of the gases are being mechanically compressed or being pushed together, causing them to rub tightly and trying to get them into a smaller piece of real estate than they were intended to have. or when you compress a gas, you have to do work on the gas to compress it...this work results in greater kinetic energy in the gas, which causes molecules to move faster, which increases the temp.
What is an example of compression in science?
Generally applies to gases, reducing the volume by doing work on the gas raises its pressure. Elastic solids can be compressed, but liquids are usually not compressible.
When a load was added to the piston the volume of the liquid did not change but the volume of the air decreased Explain why this happened?
The particles in a liquid are very close together, so an increase in pressure cannot push them any closer. The particles in a gas are widely spaced, so they can easily be forced closer together. Gases are compressible, liquids are not.
What are the properties of solids for kids?
The solids have definite shape they have definite volume they have high density they are packed ie.not compressible
Are gases the only form of matter that is compressible?
No. All forms of matter are compressible if you use sufficient pressure. Gases are the most easily compressible, but liquids are also compressible if you use high enough pressures. So are solids, believe it or not.
Name of gases that are compressible?
All gases are compressible (even all fluids and solids are, though much lesser), so there is no special name needed for this group because it is not special.
What property makes gases useful for shock absorbers in mountain bikes and cars?
Gases are compressible.
Is carbon monoxide compressible?
Yes, carbon monoxide is compressible. Like all gases, it can be easily compressed into a smaller volume by increasing pressure. This is due to the fact that gases have more empty space between their particles compared to solids and liquids.
Which of the following substances is most compressible?
Gas is the most compressible because the atoms have the most space in between. Solids are the least compressible because their atoms are tightly packed. Degree of compressibility will depend entirely on the substance in question.
What happens to volume if a material is placed under pressure?
The density increases. A lot for well-compressible substances such as gases, a little for hardly-compressible substances such as water.
what gas properties cushion the force of impact during a car accident?
Gases are compressible (;
Why solids is not compressible why?
solid is a state in which molecules are closely packed than liquids and gases. the inter molecular distance between the molecules of solids are less or negligible.thats why the solids are not compressible
What property makes gasess useful for shock absorbers in mountain bikes and cars?
Gases are compressible.
Do gases and liquids share the compressibility property?
Gases and liquid do not share the same compressibility property. In liquids, the molecules are approximately lesser compressed, that Is why they move around freely and does not have fixed shape. While gas is the most compressible and it doesn't have a shape.
Why do gasses have neigthter a fixed volumn?
Because gases are compressible, meaning their volume depends on the pressure exerted on them.
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.
