$Work done in this thermodynamic cycle (1 \to 2 \to 3 \to 4 \to 1) is | W | = \frac{1}{2} {RT}_{0}$
$The ratio of heat transfer during processes 1 \to 2 and 2 \to 3 is |\frac{Q_{1 \to 2}}{Q_{2 \to 3}}| = \frac{5}{3}$
$The above thermodynamic cycle exhibits only isochoric and adiabatic processes.$
$The ratio of heat transfer during processes 1 \to 2 and 3 \to 4 is \frac{∣ Q_{1} + 2}{Q_{3 \to 4}} ∣ = \frac{1}{2}$

The correct answers are: $text Work done in this thermodynamic cycle end text left parenthesis 1 rightwards arrow 2 rightwards arrow 3 rightwards arrow 4 rightwards arrow 1 right parenthesis text is end text vertical line straight W vertical line equals 1 half RT subscript 0$ , $text The ratio of heat transfer during processes end text 1 rightwards arrow 2 text and end text 2 rightwards arrow 3 text is end text open vertical bar Q subscript 1 rightwards arrow 2 end subscript over Q subscript 2 rightwards arrow 3 end subscript close vertical bar equals 5 over 3$
