WebJun 30, 2024 · An example is if you have 1 mol of an ideal gas that reversibly expands to double its volume at 298.15 K. Then, the reversible work that gave rise to that expansion is found using the ideal gas law for the pressure: wrev = − ∫ 2V 1 V 1 nRT V dV. = − nRT ln(2V 1 V 1) = − nRT ln2. = − 1.00 mols× 8.314472 J/mol ⋅ K× 298.15 K× ln2. Webq = DU ; w = 0 ; 3. Isobaric Process The definition of enthalpy is the it is equal to the heat during a constant pressure or isobaric process; thus q = DH. Work is found thethe first law as w = q - DU; thus. q = DH ; w = D HPVL ; 4. Isothermal Process Because U is a function only of T for an ideal gas, DU = DH = 0 for an isothermal process.
