If using a piston cylinder arrangement what we can do is use a spring instead of weights and let the gas reach equilibrium with the spring force (we can use a spring with a desired spring constant). A reversible isothermal expansion of the ideal gas is made from an initial volume V 1 to a volume V 2 at an absolute (ideal gas) temperature T 2. The amount of pressure-volume work w 2 done by the system is obtained by substituting into Equation (2.16). The result is Question: For The Isothermal Expansion Of An Ideal Gas Into A Vacuum, Q = 0, W = 0, And ΔE = 0.
To be more precise, isothermal expansion gives ∆T = 0 (no change in the temperature). When the vacuum gets expanded, it leads to the free expansion of a gas. In the case of an ideal gas, the rate of free expansion is NIL, that is, the work done is 0. The value of 0 is the result regardless of whether the process is irreversible or reversible.
B) the gas does no work. C) no heat enters or leaves the gas.

10. ※ The isothermal expansion. The model: Ideal gas. Isothermal process – T does not change. ⇨ ∆ E = 0. First, the gas in the piston undergoes an isothermal expansion to triple its initial volume. Next, the gas undergoes an isobaric contraction back to its original volume

An isothermal process is a change in the system such that the temperature remains constant. In other words, in isothermal process ∆T = 0. Free expansion of a gas occurs when it is subjected to expansion in a vacuum (p ex =0). During free expansion of an ideal gas, the work done is 0 be it a reversible or irreversible process.
False 4. True 5. False I got at least one incorrect but I'm not sure which one(s)..please help :/ 2018-01-04 · Therefore, the change in entropy of an ideal gas at a specific, constant temperature is (by integrating (2.2)): ΔST = ∫ (2) (1) dST = nR∫ V 2 V 1 1 V dV = nRln(V 2 V 1) So if the gas expands in the isothermal process, then yes, it will have increased entropy. Isothermal expansion In an ideal gas, all the collisions between molecules or atoms are perfectly elastic and no intermolecular force of attraction exists in an ideal gas because of the molecules of an ideal gas move so fast, and they are so far away from each other that they do not interact at all. Isothermal Expansion This shows the expansion of gas at constant temperature against weight of an object's mass (m) on the piston. Temperature is held constant, therefore the change in energy is zero (U=0). So, the heat absorbed by the gas equals the work done by the ideal gas on its surroundings.
