Units of work
Unit work is the amount of work done when a unit force displaces a body through unit distance in the direction of the force. In International System of units, the absolute unit of work is 'joule'. 1 joul..
Units of heat and work
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 h..

SI Unit of Work
W = F x s SI unit of F is N and that of s is m [N=Newton] 1Nm is defined as 1 joule. i.e., 1 joule = 1..
W = F x s SI unit of F is N and that of s is m [N=Newton] 1Nm is defined as 1 joule. i.e., 1 joule = 1..Work done in unit time or rate of doing work is defined as power.
Power is denoted by the letter 'P'. SI unit of power SI unit of work is joule and time is second. Therefore, SI unit of power is joule/second. 1 joule/second = 1 w..

When pure and dry H 2 gas is passed through the inlet tube, a part of the gas gets adsorbed and the excess bubbles out through the perforations. Between the H 2 gas absorbed on the surface of the metal and H + of the solution, an equilibrium is established and an electrical double layer of oppo..
Work and Heat
Work and Heat - In 1798, Count Rumford observed that the amount of heat produced is proportional to the amount of mechanical work done. Later, Dr. James Prescott Joule of Manchester, established a definite relation between the work done and the heat produced...
