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

Violates first law of thermodynamics

B

Violates first law of thermodynamics if `Q_(1)=-ve`

C

Violates first law of thermodynamics if `Q_(2)=-ve`

D

Does not violates first law of thermodynamics

Text Solution

Verified by Experts

The correct Answer is:
A
Some mechanical energy is always converted to other from of energy or total heat cannot be converted to useful work. This is first law of thermodynamics

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.

Two ideal Carnot engines operate in cascade (all heat given up by one engine is used by the other engine to produce work) between temperatures, T_(1) and T_(2) . The temperature of the hot reservoir of the first engine is T_(1) and the temperature of the cold reservoir of the second engine is T_(2) . T is temperature of the sink of first engine which is also the source for the second engine. How is T related to T_(1) and T_(2) , if both the engines perform equal amount of work?

Two Carnot engines A and B are operated in series. The engine A receives heat from the source at temperature T_1 and rejects the heat to the sink at temperature T. The second engine B receives the heat at temperature T and rejects to its sink at temperature T_(2) . For what value of T the efficiencies of the two engines are equal?

Three Carnot engines operate in series between a heat source at a temperature T_(1) and a heat sink at temperature T_(4) (see figure). There are two other reservoirs at temperature T_(2) and T_(3) , as shown, with T_(1)gtT_(2)gtT_(3)gtT_(4) . The three engines are equally efficient if :
