TOPIC:Solved Problems set-4,Thermodynamics (Physics)
While Sir solved dv/dt he wrote it equal to KT^(-1/3).But according to me it should be (2/3)KT^ (-1/3).And the final answer then should be 20R instead of 30R.Can you please clarify
sir, 300-792 = -492, Q in process d to a will be 1230.
efficiency comes out to be =70% is this correct??
