For real gases , Z≠ , PV ≠ nRT. This implies that the gas is more compressible than expected from ideal behaviour. This is also attributed to predominance of attractive forces among the molecules of these gases. Watch Previous Videos of Chap.
There will be total MCQ in this test.
Graham’s law of diffusion can be written as. For two gases undergoing diffusion at the same pressure but at two different temperatures. In Kinetic Theory of Gases Class NCERT, the topic Kinetic Theory is talked about in detail to help students understand the behavior of gases.
It explains to the students that gas consists of fast-moving particles , namely , atoms and molecules. Its pressure, P (iii) Its temperature, T (iv) The amount of the gas (i.e., mass or number of moles). A force which produces a change in configuration of the object on applying it, is called a deforming force. Mercury and Alcohol have commonly used liquids in the liquid-in-glass thermometers.
A thermometer that uses any gas, however, gives the same readings regardless of which gas is used because all gases have same expansion at low temperature.
States of Matter Class : Overview In our everyday life, we can observe four different states of matter, namely soli liqui gas and plasma. However, there are numerous other states that can be seen to exist but only under extreme conditions. The ones worth mentioning are glass and Bose-Einstein condensates. They can be compressed much.
Their intermolecular force of attraction is least. The kinetic energy of its particles is maximum. In this chapter, we shall study some common physical properties of liquids and gases.
This chapter is from Part Physics NCERT Grade Physics. How are fluids different from solids? What is common in liquids and gases ? QUESTIONS FROM TEXTBOOK. NCERT Solutions Class Physics Physics Sample Papers. Estimate the fraction of molecular volume to the actual volume occupied by oxygen gas at STP.
Volume : It is equal to express the volume of the container in terms of litre (L), millilitre (mL), cubic centimetre (cm), cubic metre (m ) or cubic decimetre (dm ). Gaseous state is a state of matter in which the substance does not have any specific shape or volume. It adopts the form and size of its container. The fundamental macroscopic properties of gases are pressure, volume, temperature and mass of the gas.
This is mainly because in a gas, molecules are far from each other and their mutual interactions are negligible except when two molecules collide. Class Physics Chapter Kinetic Theory teaches you that properties of gases are easier to understand than those of solids and liquids. Kinetic Molecular Theory of Gases :25.
