One mole of a monatomic ideal gas goes through a thermodynamic cycle, as shown in the volume versus temperature (V-7 ) diagram. The correct statement(s) is/are:
[R is the gas constant]

Work donein this thermodynamic cycle $$(1 \rightarrow 2 \rightarrow 3 \rightarrow 4 \rightarrow 1) is |W| = \frac{1}{2} RT_0$$

The above thermodynamic cycle exhibits only isochoric and adiabatic processes.

Theratio of heat transfer during processes $$1 \rightarrow 2 \rightarrow and 2 \rightarrow 3$$ is $$|\frac {Q_1 \rightarrow 2}{Q_2 \rightarrow 3}| = \frac{5}{3}$$

Theratio of heat transfer during processes $$1 \rightarrow 2 \rightarrow and 3 \rightarrow 4$$ is $$|\frac {Q_1 \rightarrow 2}{Q_3 \rightarrow 4}| = \frac{1}{2}$$
