A gas is compressed from $V_{0}$ to $\frac{V _{0}}{2}$ in three ways: process 1 isobaric, process 2 isothermal, process 3 adiabatic. For the changes in internal energy $Δ U_{1}, Δ U_{2}, Δ U_{3}$ :

Options:

Answer:

Solution:

Isobaric compression lowers $T$ ( $Δ U_{1} < 0$ ), isothermal leaves it unchanged ( $Δ U_{2} = 0$ ), and adiabatic compression raises it ( $Δ U_{3} > 0$ ). A.
