CHE 101 Chapter Notes - Chapter 9: Identical Particles, Root Mean Square, Sodium Hydroxide
Document Summary
Thus matter is classified mainly into three categories depending upon its physical state namely solid, liquid and gaseous states. Three states of matter: solid, liquid and gas. Particle motion is very rapid and also random. The characteristics of gases are described in terms of following four parameters. The mass of the gas is related to the number of moles as n = w/m. Where n = number of moles w = mass of gas in grams. M = molecular mass of the gas: volume (v): Since gases occupy the entire space available to them, therefore the gas volume means the volume of the container in which the gas is enclosed. Units of volume: volume is generally expressed in litre (l), cm 3 & dm 3. 1m 3 = 10 3 litre = 10 3 dm 3 = 10 6 cm 3 : pressure:
