Dominic made the table below to organize his notes about mixtures.
Properties of Mixtures
has no set composition
must have more than one state of matter
must have more than one substance
What mistake did Dominic make?
The title should read "Properties of Solutions" because some mixtures do not have all of the properties listed
There is a definite recipe to make each mixture, so the composition of a mixture is set.
Although it is possible to have more than one state, it is also possible to have only one state.
A single substance can be used to make a mixture if the substance is composed of more than one element.

The physical states of matter correspond to the ways in which matter can present itself in nature. These states are defined according to pressure, temperature and above all by the forces acting on the molecules. Matter, made up of small particles (atoms and molecules), corresponds to everything that has mass and occupies a certain place in space.

It can be presented in three states: solid, liquid and gas. However, in addition to the three basic states of matter, there are two more: Bose-Einstein plasma and condensate. Plasma is considered the fourth physical state of matter and represents the state where the gas is ionized. The sun and the stars are basically formed of plasma. In addition to plasma, there is still a fifth state of matter called Bose-Einstein condensate. Named after it was predicted theoretically by physicists Satyendra Bose and Albert Einstein.

It is true that a substance can have more than one physical state, however it is quite common for substances to have only one physical state and Domic does not expose it in their table. That was a mistake.
