The correct answer indicates that temperature can alter Delta G, which refers to the Gibbs free energy, but it does so indirectly. The Gibbs free energy change (Delta G) is determined by the equation ΔG = ΔH - TΔS, where ΔH represents the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.

As temperature changes, the term TΔS influences the overall value of Delta G. This means that while temperature plays a role in determining the Gibbs free energy, it does not act independently to change Delta G directly by simply doubling it or always increasing it. Instead, the relationship between temperature and Delta G can be more complex, depending on the enthalpy and entropy changes associated with a particular process. Thus, temperature affects Gibbs free energy indirectly through its influence on the entropy term in the equation.
