NEETPhysicsThermodynamics
Figure below shows two paths that may be taken by a gas to go from a state A to a state (c) In process AB , 400 ~J of heat is added to the system and in process BC , 100 ~J of heat is added to the system. The heat absorbed by the system in the process AC will be
Options
- A500 ~J
- B460 ~J
- C300 ~J
- D380 ~J
Correct answer
B. 460 ~J
Step-by-step solution
In cyclic process ABCA Q _ cycle = W _ cycl Q _ AB + Q _ BC + Q _ CA = ar. of ABC +400+100+ Q _ C A = 1 2 (2 10⁻³ ) (4 10⁴ ) Q _ C A =-460 ~J Q _ A C =+460 ~J
