Solids, liquids and gases are the three main phases of matter. Solids have a fixed crystalline structure, whereas liquids and gases are more free-flowing. The phase of matter that a given substance exhibits depends on temperature and pressure.Know More
Solids have the least internal energy of the three states of matter and are typically the coolest. The molecules of a solid are arranged in a fixed pattern independent of the surrounding area. An example of a solid is an ice cube.
Liquids do not have a fixed structure and have slightly more space between their molecules. They adapt their molecular structure to match the container in which they are stored and are subject to gravity. Liquids have a specific viscosity, or ease at which they flow. Water is one of the least viscous liquids, as water molecules move freely. When matter is in liquid form, it has more thermal energy than it does in solid form.
Gases have even more thermal energy and freedom of movement than liquids; in fact, they occupy the entire container in which they are stored. Steam is the gaseous form of liquid water. Not all compounds exhibit all three states of matter; carbon dioxide, for instance, transitions between solid and gaseous form. This is how it came to be called dry ice.Learn More
An easy example of a solid, liquid and gas is ice, water and water vapor. Solid, liquid and gas are the three main forms that matter can exist in. Solid water is ice, liquid water is water and gaseous water is water vapor.Full Answer >
The primary difference between liquids and gases is that the constituent molecules of liquids are closer together and move less than those that make up gases. Liquids and gases behave in a number of similar ways, although both differ greatly from solids.Full Answer >
Garnets, gold and graphite are all examples of crystalline solids. These items are all defined as crystalline solids by a similar molecular structure characterized by a well-defined, regular arrangement of identical unit cells.Full Answer >
There are at least 76 solid elements in the periodic table. Eleven elements are gases at room temperature, while only three are liquids. Only the first 98 elements in the periodic table exist in nature.Full Answer >
