Teaching Jharkhand (JSSC) TGT (6 to 8) Mock Test 2023-24 Physics Thermodynamics First law of thermodynamics
If dQ is the heat given to thermodynamic system and dU is its change in internal energy and dW is the work done on the system, then the first law of thermodynamics concludes that:
1
dQ = dW
2
dQ = dU - dW
3
dQ = dW + dU
4
dQ = dU
