In a thermodynamic system ' U ' represents the increase in internal energy and 'W' the work done by the system. Which of the following statement is true?
Options
- AU =- W in an adiabatic process.
- BU = W in an isothermal process.
- CU =- W in an isothermal process.
- DU=W in an adiabatic process.
Correct answer
A. U =- W in an adiabatic process.
Step-by-step solution
For an isothermal process, U =0 . According to first law of thermodynamics, Q = U + W For an adiabatic process, array rlrl & & Q & =0 & U & =- W array
