Concept:Heat capacity depends on the amount of substance, so it is extensive, not intensive.Explanation:Heat capacity is defined as $C = \frac{Q}{\Delta T}$.Its SI unit is $\mathrm{J\,K^{-1}}$, so statement (ii) is true.Since it depends on the quantity of substance present, it is an extensive property, so statement (iii) is true.Statement (i) says it is intensive, which is false.Statement (iv) gives the unit as $\mathrm{J\,kg^{-1}}$, which is the unit of specific heat capacity, so it is false.Therefore, the statements that are not true are (i) and (iv).Answer:C. (i) and (iv) only
