Consider a heat engine as shown in (figure). `Q_(1) and Q_(2)` are heat added to heat bath `T_(1)` and heat taken from `T_(2)` one cycle of engine. `W` is the mechanical work done on the engine.

If `Wgt0`, then possibillities are:

Consider a heat engine as shown in Fig. Q_(1) and Q_(2) are heat added to heat bath T_(1) and heat taken from T_(2) in one cycle of engine. W is the mechanical work done on the engine If W gt 0 , then possibilities are : a) Q_(1) gt Q_(2) gt 0 b) Q_(2) gt Q_(1) gt 0 c) Q_(2) gt Q_(1) lt 0 d) Q_(1) lt 0, Q_(2) gt 0

Consider a heat engine as shown in figure. Q_(1)and Q_(2) are heat added both to T_(1) and heat taken from T_(2) in one cycle of engine. W is the mechanical work done on the engine. If Wgt0 , then possibilities are

Consider a heat engine as shown in figure. Q_1 and Q_2 are heat added both to T_1 and heat taken from T_2 in one cycle of engine. W is the mechanical work done on the engine. If W gt 0 , then possibilities are :

A heat engine absorbs heat Q_(1) at temperature T_(1) and Q_(2) at temperature T_(2) . Work done by the engine is (Q_(1)+Q_(1)) . This data:

A heat engine works between a source and a sink maintaned at constant temperatures T_(1) and T_(2) . For the efficiency to be greatest

A heat engine absorbs 300J of heat at 627^(@)C and rejects a part of it at 27^(@)C . Find the work done by the engine.
