have
a fixed volume
and a fixed shape. cannot be compressed , because their particles are close together and have no space to move into.
Is a solids volume fixed or variable?
Solids have
a fixed shape
and occupy a fixed 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.
Do solids have a fixed volume?
Particles in a solid have fixed locations in a volume that does not change.
Solids have a definite volume and shape
because particles in a solid vibrate around fixed locations. Strong attractions between the particles in a solid restrict their motion, keeping them in place.
Is liquid a fixed volume?
Liquids have a fixed volume but no fixed shape
. Gases have no fixed volume and no fixed shape. Gases expand to fill the space available. They can also be compressed into a very small space.
Is a fixed volume a solid liquid or gas?
Three states of matter exist – solid, liquid, and gas.
Solids have a definite shape and volume
. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Why is solid volume fixed?
(a) Solids have definite shape and definite volume because
the molecules in solid are closely packed and in fixed positions
. … 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.
How do you explain fixed volume?
What does a fixed volume mean? Fixed volume is the property of liquid and solid. Which shows that
the volume of both solid and liquid remain fixed under fixed temperature and pressure
. Unlike gases, where the volume changes without applying any external force.
Which state of matter has variable volume?
Matter in the liquid state maintains a fixed volume, but has a variable shape that adapts to fit its container. Its particles are still close together but move freely. Matter in
the gaseous state
has both variable volume and shape, adapting both to fit its container.
What is the volume of a solid?
The volume of a solid is
the measure of how much space an object takes up
. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units⋅3 units⋅5 units = 30 cubic units.
Which among these will have no shape but fixed volume?
However,
liquids
are the only substances that have no fixed shape but have a fixed volume.
What do you call liquid to solid?
FreezingFreezing or solidification
is a phase transition in which a liquid turns into a solid when its temperature is lowered to its freezing point.
Does volume change from solid to liquid?
For most substances, the change from
a solid to a liquid state does not mean a big change in volume
. This is because the particles stay approximately the same distance apart. … When a gas condenses to form a liquid, its volume decreases significantly.
What does definite volume mean?
Definite (for both shape and volume) means
that the container makes no difference whatsoever
. If 5-liters of liquid water is poured into a 10-liter container, the liquid would occupy 5-liters of the container and the other 5-liters would be empty.
What has definite volume but no definite shape?
A solid has definite volume and shape, a
liquid
has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.
What are the general characteristics of a solid?
- strong intermolecular forces.
- particles vibrate in place.
- low kinetic energy (KE)
- definite shape.
- definite volume.
- incompressible.
- high density (as compared to same substance as a liquid or gas)
- low rate of diffusion (millions of times slower than in liquids)
Why does a gas not have a fixed shape and volume?
Gases do not have a definite shape or volume
because the molecules in gases are very loosely packed
, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
