physical properties of haloalkanes

As such substances are subjected to cyclic changes the loss of magnetic properties of substance must be small. Therefore the material should attain high values of intensity of magnetisation I and magnetic field for low values of the external field which is the magnetising field. For this ..

Today the fact that all matter is made up of atoms is universally accepted. Realisation of the atomic constituents of matter began in 1828 when Scottish botanist Robert Brown observed a random ceaseless motion of pollen grains suspended in a liquid. Many macroscopic properties and p..

Momentum is another vector quantity which has the same direction as that of velocity. Momentum is a property of the body possessed by virtue of its mass and velocity. It is the product of mass of the body and its velocity. Momentum = mass x velocity p = m x v S.I Unit of momentum = kg x m..

The medium must possess the following properties for the propagation of the waves: The medium should be able to return to its original condition after being disturbed, i.e., the medium must possess elasticity. The medium must be capable of storing energy. The frictional resistance must be..

This is derived from the Greek word 'dynamis', meaning power. Dynamics involves the study of the cause of motion, which is force. When we relate motion of an object to the forces associated with it and to the properties of the moving objects, we are dealing with dynamics. In this chapter..

Rutherford's alpha particle scattering experiment explained the structure of atom and the size of nucleus. The Bohr's model explained the hydrogen spectrum. Radioactivity occurs due to nuclei being unstable resulting in the emission of three types of radiations having different properties..

Satellite technology is very useful in collecting information about various factors of the atmosphere, which governs the weather and climatic conditions. An aerial photograph of the Country is shown daily on the television. It is also published daily in the newspapers. The data collected by INSAT ..

It is based on the following principles: 1) Action of sharp points: Charges are leaked from pointed ends of charged conductors. This creates an electric wind (as moving air is ionized) which moves away from the conductor. 2) The property that the charge given to a hollow conductor is tra..

The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be possible for matter, which consi..
