A gas is taken through a cyclic process ABCA as shown in, if `2.4 cal` of heat is given in the process, what is the value of J ?

A

`4.17 "J/cal"`

B

`4.4 "J/cal"`

C

`4.12 "J/cal"`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta Q = W` = area enclosed by the cycle
`=1/2 xx(700 - 500) xx10^(-6) xx(200 - 100) xx10^3 = 10J = (2.4 call )J rArr = 10/ (2.4) J//cal = 4. 167 "j/call "`
