In physics, a solid is a state of matter characterized by rigidity and resistance to changes of shape or volume. Solid objects have a definite volume, they resist forces (such as pressure, tension and shear) in all directions, and they have a shape that does not change smoothly with time. The branch of physics that studies solids is called solid-state physics. The physical properties of solids are highly related to their chemical composition and structure. For example, the melting point of ice is significantly lowered if its crystal structure is disrupted.
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, a liquid is one of the four fundamental states of matter (the others being solid, gas and plasma). A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena.

all right, so there's a lot of different examples that you can use to see that solids give off vapour pressure without any scientific instruments at all. For example, one good example would be kept gold, dry ice. A lot of people have seen the demonstration before where if you have a block of dry ice, you can see that it gives off these clouds as it supplements. Now the only reason that I can sublimate is because it's a solid that has a vapor pressure. It is releasing vapor into the atmosphere. Another example is the fact that you can smell some solids sulfur, for instance. So for is this yellow rocket doesn't smell very good at all. But the fact that you can smell it at all is because little molecules of sulfur are leaving. Little molecules of sulfur are leaving the sulfur runk and going up into the atmosphere. So there you go. Under certain circumstances, you can smell the vapors coming off of certain minerals, and under other times you can actually see the vapour pressure
