3.Work Done During Expansion: - During adiabatic expansion, the gas does work on the surroundings. Therefore, W is negative (since the gas is expanding). - This means: ΔU=W<0 -Hint: When a gas expands, it uses energy to do work, which leads to a decrease in internal energy. ...
Adiabatic expansion is a process in thermodynamics where a gas expands within a closed system without exchanging heat with the surroundings. This means that the internal energy of the gas remains constant, and the work done by the gas is equal to the change in its internal energy. How...
c) The work done from 1-2 and 3-4 is easy. To determine the work done from 2-3 use the first law: dQ = dU + dW to determine the work done (what is Q for this adiabatic expansion?). Hint: you just have to know the change in temperature - use: to find the temperature at ...

known as an isothermal expansion, involves keeping the gas at a constanttemperature. As the gas does work against the restraining force of the piston, it must absorb heat in order to conserveenergy. Otherwise, it would cool as it expands (or conversely heat as it is compressed). This is ...
that in a cycle consisting of two stages (1) an isothermal step and (2) and adiabatic step the work done on the environment is either zero (reversible) or negative (irreversible), which really nobody denies, you must do something else than just these two steps to get positive work done...
Adiabatic Expansion and Gas Liquefaction One method used to liquefy a gas lowers the temperature of the gas by causing it to expand and thereby to perform “P dV” work against its surroundings. If the expansion is adiabatic or nearly so, the work is done at the expense of the internal en...
During the adiabatic expansion of 2 moles of a gas, the internal energy of the gas is found to decrease by 2 joules , the work done during the process on the gas will be equal to View Solution The work done by 1 mole of ideal gas during an adiabatic process is (are ) given by ...
Why adiabatic expansion produces cooling? Under what conditions may one describe atmospheric processes using the incompressible form of the continuity equation? Why do we not consider the change of pressure of gas while calculating the work done? Differentiate between the adiabatic wall and the diathe...
