ideal gases and real gases

The effect of temperature on the behaviour of real gases is studied by plotting the value of 'PV' against temperature. It is observed that the deviations from ideal behaviour is less with the increase in temperature. Thus, real gases show idea..

All gases are known to exist as real gases and show ideal behaviour only to some extent under certain conditions. When PV = nRT for ideal gases, then the ratio..

. The dependence of solubility of a gas and its pressure above the solvent is given by a law known as Henry's law. This law states that 'the mass of a gas dissolved in a given mass of a solvent at a particular temperature is proportional to the pressure of the gas in equilibrium with the solution'...

In lower plants (and also protozoans) exchange of gases takes place through the general body surface as they are not highly modified or specialised. Also, the body surface allows the diffusion of gases. In higher plants the exchange of gases takes place through stomata..

when T = 0, then C = 0 This leads us to the following definition of 'absolute zero of temperature'. Absolute zero of temperature may be defined as that temperature at which the rms velocities of the gas molecules become zero. In other words, all molecular motion ceases at absolute zero of tempera..

Liquids are 10 5 times less compressible than gases but are about 10 times more compressible than solids. This is due to the fact that the molecules in liquid state are not as closely packed as in solids but are closer to each other as compared to gases. Moreover in the case o..

The Greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (referred to as greenhouse gases), trap energy from the Sun. Without these gases heat would escape back into space and living on Earth would be inh..

The molecules of the gas are in constant motion, at very high velocity. There is a great amount of intermolecular space between the molecules. When two gases are mixed, particles of one gas can easily pass through the intermolecular space of the other gas. As a result both the gases..

Gases diffuse in and out of the general surface of the roots. The gases are found in the soil surrounding the roots. Plants which grow in salty water show specialised roots called the pneumatophores. These are roots growing out of the surface of water with numerous pores on the..

The Greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (referred to as greenhouse gases), trap energy from the Sun. Without these gases heat would escape back into space and living on Earth would be inhospita..
