Thermodynamics - Result Question 13

14. Figure below shows two paths that may be taken by a gas to go from a state $A$ to a state $C$ .

In process $A B, 400 J$ of heat is added to the system and in process $B C, 100 J$ of heat is added to the system. The heat absorbed by the system in the process $A C$ will be

[2015]

(a) $500 J$

(b) $460 J$

(d) $380 J$

Show Answer

Answer:

Correct Answer: 14. (b)

Solution:

(b) In cyclic process $A B C A$

$Q_{cycle} = W_{cycle}$

$Q_{A B} + Q_{B C} + Q_{C A} =$ ar. of $△ A B C$

$+ 400 + 100 + Q_{C \to A} = \frac{1}{2} (2 \times 10^{- 3}) (4 \times 10^{4})$
