One mole of a monatomic ideal gas goes through a thermodynamic cycle, as shown in the volume versus temperature diagram. The correct statement(s) is(are) :

Options

A. Work done in this thermodynamic cycle `(1 to 2 to 3 to 4 to 1)` is `|W| =(1)/(2)RT_(0)`
B. The above thermodynamic cycle exhibits only isochoric and adiabatic processes.
C. The ratio of heat transfer during processes `1to 2` and `2 to3` is `|(Q_(1 to 2))/(Q_(2 to 3))|=(5)/(3)`
D. The ratio of heat transfer during processes `1 to 2` and `3 to 4` is `|(Q_(1 to 2))/(Q_(3 to 4))|=(1)/(2)`
