    Pankaj S. Joshi (born 25 April 1953) is an Indian astrophysicist and cosmologist whose research is mainly focused on areas of gravitational collapse and spacetime singularity. [1] He has published more than 225 research papers in national and international journals, and books and monographs on the subject.

    Bromine in both liquid and gas state, encased inside acrylic in solid state Helium 's orange glow in its plasma state A simplified phase diagram for water , showing whether solid ice, liquid water, or gaseous water vapor is the most stable at different combinations of temperature and pressure

    en.wikipedia.org/wiki/Gas

    Drifting smoke particles indicate the movement of the surrounding gas.. 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).

  6. Ideal gas law - Wikipedia

    Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...

  7. Equation of state - Wikipedia

    en.wikipedia.org/wiki/Equation_of_state

    At present, there is no single equation of state that accurately predicts the properties of all substances under all conditions. An example of an equation of state correlates densities of gases and liquids to temperatures and pressures, known as the ideal gas law, which is roughly accurate for weakly polar gases at low pressures and moderate temperatures.

  8. Water vapor - Wikipedia

    en.wikipedia.org/wiki/Water_vapor

    Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. [1]

  9. Ideal gas - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas

    The ideal gas law is the equation of state for an ideal gas, given by: = where P is the pressure; V is the volume; n is the amount of substance of the gas (in moles) T is the absolute temperature; R is the gas constant, which must be expressed in units consistent with those chosen for pressure, volume and temperature.
