Gases can't be liquified at temperatures above the critical temperature because at this point the properties of gases and liquids become the same, and there is no basis on which to distinguish between gases and liquids. The vapor pressure of a liquid at the critical temperature is called the critical pressure (Pc).

The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.

Play around with it and find out how it acts differently from a normal liquid and a normal solid. Other, more familiar substances change states (from solids to liquids to gases) when we change the temperature, such as freezing water into ice or boiling it away into steam. But this simple mixture shows how changes in pressure, instead of temperature, can change the properties of some materials. Applying pressure to the mixture increases its viscosity (thickness). A quick tap on the surface of Oobleck will make it feel hard, because it forces the cornstarch particles together.

Here is an example. When you pour a liquid from one container to another, the liquid takes the shape of the container. The volume of the liquid is the same. The properties that solids and liquids share are that they both have definite volume. Source- Mrs. Kristen Eichinger, Mrs. Cindy Surplus and my Harcourt Science book.

The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids.

The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids. 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, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

Quick Answer. Unlike gases, solids and liquids both consist of particles that are held close together and are not easily compressed. Because of this limited free space between the particles, solids and liquids are called condensed phases. Keep Learning.

Although scientists have identified five. states of matter, the most common are solids, liquids, and gases. The Solids, Liquids, and Gases unit is designed to provide students with information. and experiences related to these three states of matter. The unit addresses. how matter can change from one state to another.

Single crystalline form of solid insulin. Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). It is characterized by structural rigidity and resistance to changes of shape or volume.

There is another way of condensing a gas to form a liquid, however, which involves raising the pressure on the gas. Liquids boil at the temperature at which the vapor pressure is equal to the pressure on the liquid from its surroundings. Raising the pressure on a gas therefore effectively increases the boiling point of the liquid. Suppose that we have water vapor (or steam) in a closed container at 120oC and 1 atm.
