Oxidising Power of Halogens - Halogens have high electron affinity values and therefore they have strong tendency to take up the electro..

Summary - The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy a..

. A student carrying his bag full of books feels tired after sometime. We feel he has done work. But physics says that the work done by him against gravity is zero. Then, when is work done? Work is done by a force when the force produces a displacement in the body on which it acts, in any..

Summary - In physics, the concept of energy plays the role of the money. Work is transferred to or from an object by means of force acting on the body. Energy transferred to the body is positive work and the energy transferred from the body is negative work. Unit of work is joule. The tim..

Contamination of radioactive substances such as wastes of uranium and thorium can be carried into water from nuclear power plants, during their mining and refining processes. Scientific and medical institutions, which utilize radioactive materials can also contaminate water bodies. These..

In these, the fulcrum is in the centre with weight and power on either side. For example, the joint between the first vertebra (atlas) and occipital bone of skull exhibits first class lever, in which the joint is the fulcrum, contraction of back muscle in the effort and facial part of th..

Hot concentrated sulphuric acid acts as a powerful oxidizing agent. When heated, sulphuric acid decomposes and produces nascent oxygen, which helps in the oxidation process. It oxidizes metals as well as non-metals, and in turn gets reduced to sulphur dioxid..

Balanced And Unbalanced Forces - The figures show a block of wood on a table. When the block is pulled at point A, it begins to move towards the left and if the block is pulled at the point B it moves towards the right. Example of Balanced Forces In a game of tug of war when both the team..

In the presence of moisture, sulphur dioxide acts as a powerful reducing agent. On reaction with water it forms sulphurous acid. ..

. In the ECS, Li system has the lowest SRP and is highly electro positive which goes on decreasing down the series. 5) A metal system occurring above H 2 , displaces H 2 from dilute acids, from water steam depending on its position and gets tarnished. 6) A metal system occurring below H 2 does not ..
