Do liquids always have the same volume?
Liquids, because they flow, can occupy whatever shape their container has, so they do not have a fixed shape. Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed. They do not have a fixed volume.
Why do liquids flow differently?
The forces between liquid particles are weaker than the forces between solid particles. This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.
Why do the mass of liquids differ?
The molecules of different liquids have different size and mass. The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v.
Why liquids fill the bottom of a container?
The attraction between the particles in a liquid keeps the volume of the liquid constant. The movement of the particles causes the liquid to be variable in shape. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume.
Why a liquid has a definite volume but a gas does not?
(b) Liquids have a definite volume but no definite shape. (c) Gases have no definite volume and no definite shape. The molecules can move around and the forces of attraction between molecules is less as compared to solids, so the liquid takes the shape of the container and volume is definite.
Does the volume of a liquid change?
Liquids. Liquid: Liquids maintain a fixed volume, but their shape will mold to the shape of the container they are being held in. A liquid maintains a fixed volume, but its shape will mold to the shape of the container it is being held in.
Why do you think that the same volume of different materials have different masses?
In other words, lead is denser than the cotton. Equal volumes of different substances have different masses. This is because the particles of iron are more closely packed than those of the wood. to other words, iron is denser than wood.
Why can we not hold liquid with our bare hands?
We can not hold liquid in our open hand because interparticle force of liquid is very low so it is a fluid.
Why solids Cannot be pressed easily?
SolidsEdit They are held tightly together by strong forces of attraction. They are held in fixed positions but they do vibrate. Because the particles don’t move, solids have a definite shape and volume, and can’t flow. Because the particles are already packed closely together, solids can’t easily be compressed.
