Which of the following statements is true? ( U = increase in internal energy, dW = work done by the system)
Options
- AIn an adiabatic process U = dW
- BIn an adiabatic process U =- dW
- CIn an isothermal process U =- dW
- DIn an isothermal process U = dW
Correct answer
B. In an adiabatic process U =- dW
Step-by-step solution
We have Q = U + W In a adiabatic process, Q =0 U =- W
