A phase diagram is a graphical representation of pressure and temperature of a material. Phase diagrams show the state of matter at a given pressure and temperature. They show the boundaries between phases and the processes that occur when the pressure and/or temperature is changed to cross these boundaries.
Phases (States) of Matter with Examples. Matters can exist in four states; solid, liquid, gas and plasma. Some specific properties of these phases are given in the table below. In this unit we will examine solids, liquids and gases. Shape given below summarize the phase changes of matters from solid to liquid, liquid to gas.
Reading About Matter Matter is something that has mass and volume (takes up space). Matter can be found in several phases or states. The three most common phases of matter on Earth are solids, liquids and gases. Less commonly, we can also find matter as a plasma or Bose-Einstein (BE) condensate. Solids have a fixed shape and volume.
Introduction. A phase transition is the transition from one state of matter to another. There are three states of matter: liquid, solid, and gas. Liquid: A state of matter that consists of loose, free moving particles which form the shape set by the boundaries of the container in which the liquid is in. This happens because the motion of the individual particles within a liquid is much less ...
Iron-carbon phase diagram, showing the conditions necessary to form different phases. Distinct phases may be described as different states of matter such as gas, liquid, solid, plasma or Bose–Einstein condensate.Useful mesophases between solid and liquid form other states of matter.. Distinct phases may also exist within a given state of matter. As shown in the diagram for iron alloys ...
Phase Transitions Between States of Matter. Temperature and pressure changes may cause phase transitions between states of matter. Changes in temperature and pressure causes matter to change from one state to another. This change is called a phase transition or phase change. Examples of phase transitions including the melting of ice (a solid ...
A phase diagram represents the various states of matter under different conditions of temperature and pressure. It serves as a visual tool in thermodynamics and material science, providing insights into the behavior of substances as they transition from one state to another, such as from solid to liquid or from liquid to gas.
Figure \(\PageIndex{1}\): The three most common states or phases of matter are solid, liquid, and gas. A fourth state of matter, plasma, occurs naturally in the interiors of stars. A plasma is a gaseous state of matter that contains appreciable numbers of electrically charged particles (Figure \(\PageIndex{2}\)). The presence of these charged ...
This phase of matter is called a supercritical fluid, and the temperature and pressure above which this phase exists is the critical point (Figure \(\PageIndex{5}\)). Above its critical temperature, a gas cannot be liquefied no matter how much pressure is applied. The pressure required to liquefy a gas at its critical temperature is called the ...
4.6: Phase Transitions Phase transitions occur when energy is gained or released by a material, resulting in either more or less order arrangements of molecules. 4.7: Phase Transitions Phase transitions are processes that convert matter from one physical state into another. There are six phase transitions between the three phases of matter.

In physical chemistry, states of matter represent distinct forms that different phases of matter take on. There are four fundamental states: solid, liquid, gas, and plasma. Each state exhibits unique properties and behaviors. Solid State. Solids are characterized by their fixed shape and volume. In this state, particles are closely packed ...
matter which leads to phase changes. Lesson Content Overview Students will use their knowledge of states of matter to introduce the relative amount of kinetic energy in each state of matter, how changes in the kinetic energy can causes phase changes in matter, and what those phase changes are called. Duration 70 minutes Setting Classroom Grouping

Under high-temperature conditions, matter also can exist as a plasma. Most matter is a mixture: It is composed of two or more types of matter that can be present in varying amounts and can be separated by physical means. Heterogeneous mixtures vary in composition from point to point; homogeneous mixtures have the same composition from point to ...
This flow chart begins with matter at the top and the question: does the matter have constant properties and composition? If no, then it is a mixture. This leads to the next question: is it uniform throughout? If no, it is heterogeneous. If yes, it is homogenous. If the matter does have constant properties and composition, it is a pure substance.
Figure 1.6 The three most common states or phases of matter are solid, liquid, and gas. A fourth state of matter, plasma, occurs naturally in the interiors of stars. A plasma is a gaseous state of matter that contains appreciable numbers of electrically charged particles (Figure 1.7). The presence of these charged particles imparts unique ...
