Question

The following data show the change in internal energy of a gas, the heat transferred (into if positive) for a gas, and the work done by a gas as it goes through different processes.
Which of the following is an adiabatic process?

• A. Internal Energy Change - $213J$, Heat Transfered - $213J$, Work Done - $0J$
• B. Internal Energy Change - $0J$, Heat Transfered - $226J$, Work Done - $226J$
• C. Internal Energy Change - $113J$, Heat Transfered - $-389J$, Work Done - $-502J$
• D. Internal Energy Change - $290J$, Heat Transfered - $115J$, Work Done - $-175J$
• E. Internal Energy Change - $-213J$, Heat Transfered - $0J$, Work Done - $213J$

Answer 1

Answer: (E)

Internal Energy Change - $-213J$, Heat Transfered - $0J$, Work Done - $213J$

There is no exchange of heat between the system and the surrounding $(Q=0)$ in an adiabatic process.

Thus option E is an adiabatic process.
