![]() ![]() However, the structure also contains a second set of potassium atoms that are in a fluid arrangement. Novel structureĪpplying high pressures and temperatures to potassium – a simple metal – creates a state in which most of the element’s atoms form a solid lattice structure, the findings show. Researchers have found, however, that some elements can, when subjected to extreme conditions, take on the properties of both solid and liquid states. Until now, the atoms in physical material were understood to exist typically in one of three states – solid, liquid or gas. In modern science or technology, the plasma state of matter can be used for making television or many electronic devices.Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously. It has gaseous ions, molecules, or atoms that contain positive or negatively charged particles.Īrtificially, the plasma state of matter is created or generated by subjecting natural gas to a strong magnetic field or heating natural gas. Like gases, plasma state has no fixed shape and volume and is less dense than liquid or solid-state. Plasma states of matterĪ plasma state is one of the four fundamental states of matter like solid, liquid, and gases. ![]() Gases have properties to obey some simple common pressure, volume, temperature, and mole number relation. In the gaseous state of matter, the thermal expansion is also the same. All the gases are found to expand to the same extent when heated to the same interval of temperature. The forces of attraction amongst them are not sufficient to bind the molecules in one place. Molecules in a gaseous state move at very high speeds. If the thermal energy is much greater than the forces of attraction, then we find the gaseous state of matter. Low density and high compressibility are also the characteristics of gases. In gaseous states, the matter has the property of filling any available space to a uniform density. The gaseous state of matter is characterized by a lack of definite volume and shape. In fact, a liquid has some of the properties of solid and gas. Therefore, the liquid state is the intermediate between the gaseous and solid states of matter. On cooling a gas changes into the liquid state and further cooling, the liquid freezes into the solid states. ![]() In general, the liquid state is more denser and less compressible than gases. They take the shape of the vessel in which they are placed. Due to this fact, liquid has a definite volume, but that does not have a definite shape. The liquid molecule has kinetic energy but it cannot go very far due to larger forces of attraction amongst them. In a liquid state, the forces of attraction are greater than the thermal energy. Therefore, liquid can adapt the shape of the container where it can be placed. Matter in the liquid state has a fixed volume but it contains variable shapes. It changes to liquid with the addition of heat energy.Solids differ from liquid and gases in respect of size, shape, and volume.Therefore, they can vibrate about their mean position. The molecules in the solid state do not possess any translational energy.The position of the molecules remains fixed in the solid state.In solid state of matter, the forces of attraction between the atoms, ions, or molecules are much greater than the thermal energy.The solid state of matter has the following properties, Therefore, component particles like atoms, ions, or molecules are closed together and arranged in a fixed place. The solid state of matter has a definite volume and shape. Another is disruptive forces due to the thermal energy of the molecules.One is molecular forces of attraction which tend to hold the molecules together.Two types of opposing molecular forces derive the states of matter. If heat is high enough, the state is entered into plasma. Similarly, liquid changes to a gas at its boiling point. Solid is changing to liquid at its melting point. Therefore, heat is added to the substances to change the states of matter from solid to liquid to gas to plasma. The states or phases of matter can change depending on the conditions like pressure and temperature.įor example, solid state changes to the liquid or gas, or plasma by increasing temperature. ![]() We observed these states by daily human experience. ![]()
