Document Summary
The perfect gas: gas: a form of matter that fills any container it occupies. Equation of state of a perfect gas: p= nrt/v where r is mass density: pressure (p)= f/a to which theforce is applied f= mg, m= r v, The greater force acting on a given area, the greater the pressure. If two gases are in separate containers that share a common movable wall, the gas that has the higher pressure will tend to compress the gas that has lower pressure. Mechanical equilibrium: when the two pressures are equal and the wall has no tendency to move (high pressure lowers and low pressure increases). Barometer: measures the pressure exerted by the atmosphere. Hydrostatic pressure (p)= r gh, where g is gravity and h is the. Bayard-alpert pressure gauge: interpretation of pressure is based on the ionization of molecules present in the gas and the resulting current of ions.
