Give the process which are quasi-static and do not dissipated energy.

What is quasi-static ?

Name the process which is associated with dissipated energy process and reduce the efficiency.

The spheres of radius r and R having charge q and Q respectively on them . When they are joined with conducting ,wire, the energy of this system does not dissipated then ...........

Give any four illustrations of the kinetic energy.

Column I gives some devices and Column II gives some processes on which the functioning of these devices depend. Match the devices in Column I with the processes in Column II and indicate your answer by darkening appropriate bubbles in the 4 xx 4 matrix given in the ORS.

Explain Quasi-static process.

If 2.2 kW of power having 22000 V is transmitted on a transmission line with 10 Omega resistance then power dissipated in the form of thermal energy will be ……

An ideal gas under goes a quasi static, reversible process in which its molar heat capacity C remains constant. If during this process the relation of pressure P and volume V is given by PV^n=constant , then n is given by (Here C_P and C_V are molar specific heat at constant pressure and constant volume, respectively):

The internal energy of a system remains constant when it undergoes (i) a cyclic process (ii) an isothermal process (iii) an adiabatic process (iv) any process in which the heat given out by the system equal to the work done on the system
