Quizplus · Accepted Answer

When a gas undergoes expansion, the volume increases, leading to a decrease in molecular collisions as molecules have more space to move around. This does not inherently increase the gas's pressure or temperature; in fact, pressure may decrease if the volume increases while the amount of gas and temperature remain constant. Temperature changes depend on the type of expansion (adiabatic, isothermal, etc.) and are not a direct consequence of expansion alone.
