A cycle followed by an engine (made of one mole of an ideal gas in a cylinder with a piston) is shown in the figure. Find heat exchanged by the engine, with the surroundings at constant volume of the cycle. `(C_v = (3/2) R)

A heat engine carries one mole of an ideal monoatomic gas around the cycle as shown in the figure, the amount of heat added in the process AB and heat removed in the process CA are :

Three capacitors C_1,C_2 and C_3 are connected to a battery of 6 V as shown in the figure find the charge on three capacitor

Consider a PV-diagram in which the path followed by one mole of perfect gas a cylindrical container is shown in (fig.). Find the work done when the gs is taken from state 1 to state 2.

If one mole of an ideal gas (C_(p.m.)=(5)/(2)R) is expanded isothermally at 300K until it’s volume is tripled, then change in entropy of gas is:

For an ideal gas V - T curves at constant pressure P_(1) & P_(2) are shown in figure, from the figure

Consider a PV-diagram in which the path followed by one mole of perfect gas a cylindrical container is shown in (fig.). Given to internal enregy for one mole of gas at temperature T is (3 // 2) RT,find the heat supplied to the gas when it is taken from state 1 to 2,with V_2=2V_2 .

One mole of an ideal gas at 25^(@)C expands in volume from 1.0 L to 4.0 L at constant temperature. What work (in J) is done if the gas expands against vacuum (P_("external") = 0) ?

A metal bar AB can slide on two parallel thick metallic rails separated by a distance l. A resistance R and an inductance L are connected to the rails as shown in the figure. A long straight wire carrying a constant current I_(0) is placed in the plane of the rails and perpendicular to them as shown. The bar AB is held at rest at a distance x_(0) from the long wire. At t=0, it is made to slide on the rails away from wire. Answer the following questions. Find a relation among i, (di)/(dt) and (d phi)/(dt) , where i is the current in the circuit and phi is the flux of the megnetic field due to the long wire through the circuit.

If one mole of an ideal gas C_p = 5/2 R is expanded isothermally at 300 k until it's volume is tripled., if expansion is carried out freely (P_(ext)=0), then DeltaS is :
