Kinds of pressure :

• degeneracy pressure (3 facts) - Pressure in a degenerate electron or neutron gas., Pressure in a degenerate electron or neutron gas.
• magnetic pressure (2 facts) - The pressure exerted by a magnetic field on the material that contains the field. in gaussian units it is given by p_m = b² / 8π, where b is the magnetic field strength.
• radiation pressure (2 facts) - The transfer of momentum by electromagnetic radiation incident on a surface: p_rad = (4/3)σT⁴ / c.
• ram pressure (2 facts) - Motion of a blunt body at supersonic velocity through an ambient gaseous medium causes a strong drag or ram pressure to be exerted on the body. In the case of a galaxy moving through the intergalactic gas, the ram pressure is capable of stripping the galaxy of much of its interstellar gas.
• zero-point pressure (2 facts) - The pressure contributed by degenerate electrons, which do not come to rest even at absolute zero.
