Solids are the only phase of matter which have a fixed shape and volume.
There is no such state of matter. You might be thinking of a liquid, which has a definite volume but no definite shape.
Obviously, the liquid phase has definite volume but indefinite shape as it is normally observed that when liquid water is poured in a glass, it adopts the shape of glass prior to any change in volume.
Yes it has neither.
liquid has no definite shape and a solid has no definite shape or volume
The gas phase of matter has no definite volume and fills the entire space available to it. Gas particles move freely and are not confined by a specific shape or volume.
Solid.
A state of matter having definite volume but no definite shape is called, "liquid".
a solide has a shape of its shape and volume
a solide has a shape of its shape and volume
a liquid
liquid
gas
gaseous phase
Gas
That's a "gas" (or a plasma).
The solid phase of matter has a definite volume and shape. Gas form has neither volume, nor shape, and liquid form has volume, but conforms to the shape of the container it is put in.
Either solid (if it also has a definite shape) or liquid (if it doesn't).
