Document Summary
The state at which a certain substance exists, depends on its temperature and pressure. heat heat. Takes the shape of the container attract/repel each other. 0. 641 ml 1 g gaseous co2 at 00c ~550 ml. The physical laws that govern the behavior of the gases are the same irrespective what that gas is. Some of the characteristics of gases are pressure and volume (e. g. volume of air and its pressure in the tire. ) = 1/2 mu2 where : m = mass, u = velocity. Recall the assumptions for an ideal gas: gas molecules move in straight lines mostly in empty space, gas molecules behave independently of each other, the total translational kinetic energy of the gas remains constant. The pressure exerted by a gas in a confined volume , v , containing an n molecules of a gas at a constant temperature is given by: P = mu2 where : n = # of molecules.
