WebTable B-1 (continued): Properties of Saturated Water, Presented at Regular Intervals of Temperature Specific volume (m3/kg) Specific internal energy (kJ/kg) Specific enthalpy … WebExplanation: To determine the enthalpy change associated with dissolving solid NaOH in water, we can use the following equation: Δ H = q / n. where ΔH is the enthalpy change (in kJ/mol), q is the heat absorbed or released (in kJ), and n is the number of moles of NaOH dissolved. To calculate q, we can use the following equation: Web2 de feb. de 2024 · Since solubility of sugar in water increases with temperature, the change in enthalpy of the sugar-water system is positive. Since the sugar-water system is absorbing heat(at constant pressure, change in enthalpy is the heat absorbed) and since entropy change of an irreversible process is greater than that in an reversible process, … miles from ludington mi to petoskey mi
