Question

$550kJ$ cycle${}^{-1}$ work is done 1 mol of an ideal gas in a cyclic process. The amount of heat absorbed by the system in one cycle is:

• A. $550kJ$
• B. $590kJ$
• C. $1100kJ$
• D. zero

Answer 1

The correct option is A $550kJ$

As the internal energy is a state function so it will be zero in the case of the cycling process.

Applying first law of thermodynamics-

$\Delta U=q-W$

$q=W$; As the $\Delta U=0$

$\therefore q=550kJ$
