\textbf{Hint: Temperature is a state function.} \textbf{Explanation:} \text{Examples of extensive properties include:} - \text{amount of substance, n} - \text{energy, E} - \text{enthalpy, H} - \text{entropy, S} - \text{Gibbs energy, G} - \text{heat capacity, } C_p - \text{Helmholtz energy, A or F} - \text{internal energy, U} - \text{Volume, V} \text{Intensive properties include temperature, T; refractive index, n; density, } \rho \text{; and viscosity, } \eta \text{.} \text{Let us analyze each option:} - \text{Temperature: This is an intensive property - it does not depend on the amount of substance present.} - \text{Volume: This is an extensive property - it depends on the amount of substance. If you double the amount of substance, the volume doubles.} - \text{Refractive index: This is an intensive property - it is characteristic of the material and does not depend on amount.} - \text{Viscosity: This is an intensive property - it is a characteristic of the material independent of amount.} \text{Extensive properties depend on the amount or size of the system, while intensive properties depend only on the nature of the substance.} \text{Thus, option 2 is the correct answer.}
