Actually liquids CAN change volume - they just change less drastically than gases under the same conditions. An obvious example is the functioning of a thermometer. The liquid in the thermometer expands (changes volume) as it gets warmer. Usually the liquid will be in a large reservoir with a narrow tube attached because the volume change is not that big. The change in volume for a gas with the same change in temperature is much more noticeable. Liquids also change their volume with changes in pressure. Again, gases change a lot more than liquids with the same change in pressure - except near the critical point of the liquid. As an example: liquid water at 50 bar and 25 °C will have a density of about 1000 kg/m3. If the pressure is cut in half to 25 bar at 25 °C, the density drops to about 998 kg/m3 - a change of about 0.2%. If you do the same with a gas at 25 °C, the density will change by 50% (250 times the change in the liquid)!
The simple reason for this is that liquids are much more dense than gases. The molecules are much closer together so when you start to put pressure on them, they resist compression much more than gases will because they are already so close and repulsive forces between the molecules are much stronger. When pressure is dropped, liquids expand less because - again - the molecules are close together and the attractive forces are much more significant. The spacing of molecules in a liquid is a bit like the situation with Goldilocks - they don't want to be too close or too far apart - they want to be "just right" in their spacing.
the volume of a gas can change, but the volume of a solid cannot change. explain why tis statement is true
because the solids and liquads molecules are closer where as the gases dont have too much close molecules
why cant liquids change volume but gases can
It turns out that gasses are the easiest form of matter to change volume. Gasses can change their volume when their temperature or the pressure on them changes.
The forces holding atoms together are stronger in a liquid than in a gas
That's because they are quite easily compressible. There are no forces holding the gas particles together. (apex)
In terms of gases, a fixed volume would mean that the pressure, temperature and the number of molecules can change but the volume, or area in which the molecules lie, must remain constant
does gas take the shape of it's container and can change volume
No lol they cant talk
Water vapor is a gas, and like all gases, it has no definite shape or volume. It will expand to fill whatever volume there is. The only thing that will change as this happens, is that the pressure exerted by the gas will change.
No, nothing can have a negative volume. No such thing.
The intermolecular strength is higher in liquids than in gases.
A change in volume with a constant, unchanging Pressure and Temperature results in increased or decreased density, inversely dependent on increase or decrease in volume.
You cant change it Answer You can't change it *easily*.
ANSWER unlike solids, both liquids and gases can change their shape to fit the container in which they are held. however, gases can also change volume unlike liquids.
the forces holding atoms together are stronger in a liquid than in gas. sdw
YEs
Gasses and plasmas.
nnoo

You cant change the volume but you can turn sound up, there is a little picture of a speaker in the top left corner click it to turn it off and on
Yes. Air is a gas, gasses are fluids, and fluids have volume.
