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

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

Answer

Brief Explanations:

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 system), $\Delta U>0$. Internal energy is related to temperature ($\Delta U = nC_{v}\Delta T$ for an ideal gas), so an increase in internal energy means an increase in temperature.

Answer:

The temperature of the system increases.
