Question

in an adiabatic process, what happens when gases in a system are compressed? the system absorbs all of the heat the system releases all of the heat. the temperature of the system increases. the temperature of the system decreases.

Explanation:

In an adiabatic process, there is no heat exchange with the surroundings ($Q = 0$). When gases are compressed, work is done on the system. According to the first - law of thermodynamics $\Delta U=Q + W$. Since $Q = 0$ and $W>0$ (work done on the system), $\Delta U>0$. An increase in internal energy $\Delta U$ leads to an increase in temperature for an ideal gas.

Answer:

The temperature of the system increases.
