The three processes in a thermodynamic cycle shown in the figure are: Process 1⟶ 2 is isothermal; Process 2⟶ 3 is isochoric (volume remains constant); Process 3 ⟶ 1 is adiabatic. The total work done by the ideal gas in this cycle is 10 J. The internal energy decreases by 20 J in the isochoric process. The work done by the gas in the adiabatic process is –20 J. The heat added to the system in the isothermal process is
