An ideal gas is taken through a cyclic thermodynamic process through four steps. The amounts of heat given to the system in thes
e steps are Q{1} = 1000J, Q{2} = - 800J, Q{3} = 450J , Q{4} = - 200 J respectively. The efficiency of cycle is nearly Need full Explanation ! Answer is already marked in attachment just need the explanation or the way to reach the answer .
