Kirchhoff's Law - 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 bod..

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. Gases have l..

Graham's law is useful in: Separation of gases having different densities by diffusion. Determining the densities and molecular masses of unknown gases by comparing their rates of diffusion with known gases. Separating the isotopes of some of the element..

Is Newton's third law of motion applicable to gravitational force? Yes it is. Let us now see how Newton's third law of motion is applicable to the gravitational force existing between the various objects in the universe. According to Newton's third law of motion to eve..

Pure translation (fixed direction) Pure rotation (fixed axis) Position x Angular position θ Velocity v = dx/dt Angular velocity ω= dθ/dt Acceleration a = dv/dt Angular acceleration α= dω/dt Mass m Rota..

To prevent adulteration and to maintain availability of good quality food stuff, the government has set up certain institutions for standardization. They are: Codex Alimentarius Prevention of Food Adulteration Act (PFA) The Agmark Standards Bureau of Indian Standards (BIS) These inst..

This law is used in comparing the temperature of any two or more systems by the common use of thermometer. For example, in order to compare temperature of two bodies X and Y, the thermometer (analogous to body C) is allowed to come into thermal equilibrium first with ..

Pollution of Water - Pollution of the environment is a major global problem of today. It is heartening to note that in the last 25 years or so, scientists and environmentalists have created a great deal of awareness on environment pollution. Several national and international laws and cha..

Assumptions stated by Classius - All the molecules of a gas are identical with respect to their shape and mass. The molecules of different gases are different. The gas molecules behave as rigid, elastic and smooth spheres. The size of gas molecules is very less when compared to the interm..

We are already familiar with set theory and mathematical logic from earlier classes. It has already been seen that there is a similarity between the laws stated in set theory and the mathematical logic. The operations 'union', 'intersection' and 'complement' on sets are comparable..
