dQ-dW=1 which of the law is obeyed by the equation..

Answer / justahelper

The first law tells us that energy is neither created nor
destroyed i.e cyclic integral of dQ should be equal to
cyclic integral of dW about a closed cycle

Then, the 2nd law clarifies this relation by specifying that
heat HAS to be rejected in the conversion of heat to work
and all heat supplied cannot be converted to work, some heat
will be stored as internal energy
Hence, dQ-dW=1 means dW work is done out of dQ and the
remaining 1 is the increase in internal energy. Hence, 2nd
law is obeyed here.

dQ-dW=1 which of the law is obeyed by the equation..

Answer / sneha more

if the eqn is for process then it obeys first law.
dQ-dW=1 dU=1

if eqn is for cycle then it obeys second law

since,
dQ & dW should not be equal

Is This Answer Correct ?    2 Yes 2 No

dQ-dW=1 which of the law is obeyed by the equation..

Answer / ronnie

answer #5 is correct.
here dQ = 1-dW so
dQ is not equal to dW
hence second law of thermodynamics is obeyed....

Is This Answer Correct ?    2 Yes 2 No

dQ-dW=1 which of the law is obeyed by the equation..

Answer / anil kumar satri

first law of thermodynamics
for open system dq = dw

so dq-dw=1
dq= dw
