Gas, one of the three fundamental states of matter, with distinctly different properties from the liquid and solid states. The remarkable feature of gases is that they appear to have no structure at all.
Gas is one of the four fundamental states of matter. The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma.
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have a lower density than other states of matter, such as solids and liquids. There is a great deal of...
A gas is a state of matter lacking either a defined volume or defined shape. Like a liquid, a gas takes the shape of a container. Unlike a liquid, a gas easily expands or contracts to fill the entire volume of the container.
Explore the interactive simulation of matter states and learn about phase changes, temperature effects, and atomic interactions.
A gas is a state of matter characterized by particles that lack both a definite volume and shape. It is one of the fundamental states of matter, alongside solids, liquids, and plasma. Positioned between the liquid and plasma states under ordinary conditions, gases can be composed of single-element atoms (e.g., H 2 , Ar), compounds (e.g., HCl ...
Explore the basics of states of matter with interactive simulations in a game-like environment on PhET.
Gas is one of the three principle states of matter. The properties of gases are distinctly different from those of liquids and solids —the other principle states. Gases have neither a definite volume nor a definite shape.
A gas is defined as a state of matter consisting of particles that have neither a defined volume nor defined shape. It is one of the four fundamental states of matter, along with solids, liquids, and plasma. Under ordinary conditions, the gas state is between the liquid and plasma states.
