WebEx. delta U= (3/2)nR (delta T), delta T is 0, so the right side is equal to zero because you are multiplying the (3/2)nR by 0. This gives you the negative work (or Wout). So, for adiabatic delt U=work. If you remove pebbles and it expands, the temperature will go down because no heat is added. This is work out, or negative work. WebJun 10, 2024 · $\begingroup$ It's not that the universe "knows" exactly how much to heat the gas, it's that a large thermal reservoir is in contact with the system and keeps its temperature constant (e.g., because the heat transfer is efficient and because any internal processes are sufficiently small and slow). Because they internal energy of an amount of …

Isothermal processes are especially convenient for calculating changes in entropy since, in this case, the formula for the entropy change, ΔS, is simply where Qrev is the heat transferred (internally reversible) to the system and T is absolute temperature. This formula is valid only for a hypothetical reversible process; that is, a process in which equilibrium is maintained at all times.
