Heat energy absorbed by a system is going through a cyclic process shown is Fig. 15.9.3.

Options

A. `10^(7) pi J`
B. `10^(4) pi J`
C. `10^(2) pi J`
D. `10^(-3) pi J`

Answer

C

Explanation

c. As `Delta U = 0` in cyclic process,
`Delta Q = Delta W =` area of circle `= pi r^(2)`
or `Delta W = 10^(2) pi J`
