Work and Measurement of Work - Let us now discuss the conditions to be satisfied for work to be done. From the above examples, it is clear that work is said to be done when a force acts on an object and the point of application of the force moves in..

Work and Measurement of Work - Work is said to be done when a force acts on an object and the point of application of the force moves in the direction of force. Conditions to be satisfied for work to be done: Some force must act on the object The po..

The heat changes are measured in calories (cal), kilo calories (kcal), joules (J) or kilojoules (kJ). These are related as: 1 cal = 4.184J 1 kcal = 4.184kJ The S.I. unit of heat is joule or kilojoule Work is measured in terms of ergs or joules. I Joule = 10 7 ergs. 1..

Work Energy Theorem - According to this principle, work done by a force in displacing a body, gives the measure of the change in kinetic energy of the body. When a force does some work on a body, the kinetic energy of the body increases by the same amount. Co..

We have learnt that of DG is a measure of the spontaneity of a chemical reaction. It can be shown that the free energy of a process is equal to maximum possible work that can be derived from the proces..

We have learnt that of D G is a measure of the spontaneity of a chemical reaction. It can be shown that the free energy of a process is equal to maximum possible work that can be derived from the process as given below: From first law of thermodynamics, it is known that D E = q ..

Electric Fuse - An electric fuse is a device which is used to limit the current in an electric circuit. The use of a fuse is to safeguard the circuit and the appliances connected in the circuit from being damaged. Parts of an Electric Fuse Working of a Fuse W..
