If U and W represent the increase in internal energy and work done by the system respectively in a thermodynamical process, which of the following is true?
Options
- AU =- W , in a adiabatic process
- BU = W , in a isothermal process
- CU = W , in a adiabatic process
- DU =- W , in a isothermal process
Correct answer
A. U =- W , in a adiabatic process
Step-by-step solution
From first law of thermodynamics Q= U+ W For adiabatic process Q=0 U=- W
