In a thermodynamic system, U represents the increases in its internal energy and dW is the work done by the system then correct statement out of the following is
Options
- AU = dW is an isothermal process
- BU =- dW is an adiabatic process
- CU =- dW is an isothermal process
- DU = dW is an adiabatic process
Correct answer
B. U =- dW is an adiabatic process
Step-by-step solution
For an isothermal process, U =0 . According to first law of thermodynamics, Q = U + dW For an adiabatic process, Q=0 U =- dW It is an adiabatic process.
