Delta S represents the change in entropy of a system. In the equation delta G = delta H - T delta S, it is used to determine the contribution of entropy to the overall change in Gibbs free energy. A negative delta S value suggests a decrease in the disorder of a system.
To determine the delta H of a reaction, one can use calorimetry to measure the heat released or absorbed during the reaction. This involves measuring the temperature change of the reaction mixture and using it to calculate the heat exchanged. The delta H value represents the change in enthalpy of the reaction.
The enthalpy change (H) when water transitions from a liquid to a gas is known as the heat of vaporization. This value is approximately 40.79 kJ/mol at standard conditions.
Delta H represents the change in enthalpy of a system. In the equation ΔG = ΔH - TΔS, it is the enthalpy change of the system. It indicates the heat absorbed or released during a reaction at constant pressure.
The standard enthalpy change of a reaction (delta H) is related to the standard enthalpy of formation (delta Hf) of the products and reactants involved in the reaction by the equation: delta H = Σ(Products delta Hf) - Σ(Reactants delta Hf). This equation relates the enthalpy change of a reaction to the enthalpies of formation of the substances involved in the reaction.

Delta S represents the change in entropy of a system. In the equation delta G = delta H - T delta S, it is used to determine the contribution of entropy to the overall change in Gibbs free energy. A negative delta S value suggests a decrease in the disorder of a system.
The delta H fusion, or enthalpy of fusion, represents the amount of energy required to convert a unit mass of a solid into a liquid at its melting point without changing its temperature. To calculate the energy needed to melt a specific mass of solid, you multiply the mass of the solid by the delta H fusion value. The formula can be expressed as ( Q = m \times \Delta H_f ), where ( Q ) is the energy required, ( m ) is the mass, and ( \Delta H_f ) is the enthalpy of fusion. This calculation provides the total energy necessary to achieve the phase transition from solid to liquid.
It is not. The density and mass would be used to find the volume.
