practice problems about graham's law of diffusion

From kinetic theory, Since the rate of diffusion of a gas is determined by the molecular speed,..

Gases have the tendency to spontaneously intermix and form a homogenous mixture without the help of external agency. This is due to the presence of large amount of empty space between the gas molecules that makes their movement rapid into each other. The gases move from a region of higher concentr..

A body that is a good radiator (or emitter) is also a good absorber. To understand this, suppose isotropic (i.e., equal in all directions) thermal radiation is incident on a body. Let a be the fraction of the total thermal radiation of all wavelengths absorbed by the body. The remaining fraction is..

Summary - Gases are different from solids and liquids. They have no definite shape or volume. When pressure is applied, a gas contracts and when pressure is released, the gas expands. Gases can move in all directions and completely diffuse with other gases to form a homogenous mixture. Ga..

In this section, we describe four specific kinds of thermodynamic processes that often occur in practical situations. These can be summarized briefly as no heat transfer or adiabatic, constant volume or isochoric, constant pressure or isobaric, and constant temperature or isothermal. For ..

Renewable sources of energy are produced continuously in nature and are non-depletable. Sources like water, sunlight, air, tidal energy, nuclear energy, geothermal power, are not exhaustible. A non-renewable source of energy gets depleted over a certain period of time, and is not easily replaceabl..
