Stronger the forces of intermolecular attraction (cohesive forces) greater is the surface tension. In liquids the molecules of the matter are held together by strong intermolecular forces in comparison to those in gases. Real gases behave, ideally at low p and high T. Comparison of volumes of two different gases effused/diffused during the same time interval. A is always positive and increases with rise of temperature. pV = nRT Distinction between three states of matter: So helping notes for neet . Necessary cookies are absolutely essential for the website to function properly. Thus matter is classified mainly into three categories depending upon its physical state namely solid, liquid and gaseous states. At low pressure only A (which  is equal to RT) is important, the others cancel out. Since none of the gases present in the universe strictly obey the equation pV =nRT. Easily compressible due to excess space between the particles of gas which compresses on applying pressure. The magnitude of surface tension of a liquid depends on the attractive forces between the molecules.
