For an adiabatic expansion of an ideal gas

WebNov 1, 2024 · In an adiabatic process with $q =0$, we find $\Delta U < 0$. When the system is an ideal gas, the end temperature will be lower than the starting temperature. For any force greater than $F_ {FE}$, the system expands against a net negative (outward pointing) pressure. The system has work done on it. We find the term $w > 0$. WebA quasi-static, adiabatic expansion of an ideal gas is represented in Figure 3.14, which shows an insulated cylinder that contains 1 mol of an ideal gas. The gas is made to expand quasi-statically by removing one grain of sand at a time from the top of the piston. When the gas expands by dV, the change in its temperature is dT.
