Relation between B and van der Waals constant is, CRITICAL PHENOMENON AND LIQUEFACTION OF GASES. Temperature: The deviation is more at low temperature and H and He always shows positive deviations at O°C. Normal or standard temperature & pressure means 0°C or 273.15 K and 1 atm pressure. In liquids the molecules of the matter are held together by strong intermolecular forces in comparison to those in gases. Surface tension decreases as the temperature increases. States of Matter . So helping notes for neet . CGS unit of coefficient of viscosity is poise When a gas is collected over water, its observed pressure is equal to the sum of the pressure of dry gas and the pressure of water vapour (aqueous tension) then. 1 mole of HCl (g) 2. These stateS are interconvertible. Physicswallah Handwritten Notes. It means gas will not exist, which is not possible. It also takes place through a porous vessel.

The temperature of gas must be lower than its critical temperature, T, Liquefaction is further based on the following principles, Cooling by adiabatic expansion (Claude’s Method). SI unit of temperature is Kelvin (K), T (K) = t°C+ 273 It is found in molecules in which highly polar bonds are present N-H, O-H, Or H-F bonds are present. The molecular motion is called thermal motion of molecules. It is given by. It acquires the shape of the container in which. t is the time taken for the gas 1 for effusion/diffusion of volume V and t2 is the In such case, Z >1, gas is less compressible. Tb = a/bR The intermolecular forces are not very strong and thus the molecules are always in constant random motion. Everything in our surroundings is called matter. Measurable properties of gases : P,V, T, n, Viscosity, specific heat are some measurable properties. : At 1 bar pressure the boiling temperature is called standard boiling point. The liquids having weak intermolecular attraction have greater tendency of escaping from the liquid surface in comparison to liquids having stronger forces of intermolecular attraction. but definite volume due to weaker intermolecular force of attraction than solids. We hope these Physics Notes for Class 11 will help you understand the important topics and remember the key points for the exam point of view. The volume of a given mass of a gas is inversely proportional to its pressure at a constant temperature. The volume occupied by gas molecules is negligible as compared to the total volume of the gas. its value depends on the mass, temperature, and nature of the gas. Real gases behave, ideally at low p and high T. Comparison of volumes of two different gases effused/diffused during the same time interval. Andrew’s Isotherms:  Isotherms of CO2 at different temperatures. The greater the value of ‘a’, the greater the strength of van der Waals forces. The state of a matter depends on the intermolecular forces and arrangement of molecules. Water droplets appear on the outer surface of a glass containing ice-cold water.

It is symbol  γ (gamma); We measure it with the help of an apparatus,  stalagmometer. This is due to the fact that intermolecular forces of attraction in them are negligible. It's an important chapter of Structural Organisation in Plants and Animals unit. They are the weakest intermolecular forces .there forces increases with, I. : The number of collisions experienced by molecules per cc of a gas per second is known as collision frequency  of gas, :  Number of collisions undergone by a molecule with other molecules per second present in 1cm, N = Number of molecules per unit volume of the gas, : The average distance travelled by the molecule between two successive collisions, It is defined as the ratio of the increase in volume of  the gas at constant pressure per degree rise of temperature to its volume at 0°C, is found  be 1/273 for all gases (charle's law), It is defined as the ratio of the increase in pressure of the gas at constant volume per degree rise of temperature to its pressure at 0°C, The value found by Ragnault & Gay Lussac was in the vicinity of, The total volume of a mixture of non reacting gases at constant temperature and pressure is equal to the sum of the individual partial volumes of the constituents, It is the number of molecules present in 1cc of a gas or vapour at STP. Increase of pressure and decrease of temperature tend to cause liquefaction of gases. Dipole-dipole interaction forces act between the molecules possessing permanent dipoles. Velocities and directions of molecules keep on changing due to intermolecular collisions. It deviates at very high pressure and very low temperature. Pressure correction, p = n2a/V2  or a = pV2/n2 = atm L2  mol-1, At very low pressures or at very high temperatures There are no attractive forces between the gas molecules.      (c) – 33°C                                                         (d) 89.5°C.
