A system is taken from state a to state c along the path adc (figure). The amount of heat absorbed is 10 cals and work done on the gas is 138 J . Calculate the work done on//by the gas when 20 cals of heat are absorbed in taking the system from state a to state c along the path abc

A thermodynamic system is taken from an initial state I with internal energy U_i=-100J to the final state f along two different paths iaf and ibf, as schematically shown in the figure. The work done by the system along the pat af, ib and bf are W_(af)=200J, W_(ib)=50J and W_(bf)=100J respectively. The heat supplied to the system along the path iaf, ib and bf are Q_(iaf), Q_(ib),Q_(bf) respectively. If the internal energy of the system in the state b is U_b=200J and Q_(iaf)=500J , The ratio (Q_(bf))/(Q_(ib)) is
