Which of the following statements about thermodynamic properties and processes is correct?
Heat capacity is an extensive property that depends on the size of the system.
Temperature is an extensive property and can vary with the amount of substance.
The enthalpy change of a reaction indicates whether it is exothermic or endothermic.
A thermochemical equation does not require the physical state of the substances to be specified.
Correct Answer
Detailed Explanation
Heat capacity is indeed an extensive property because it depends on the size and nature of the system, as indicated in the context. Temperature, however, is an intensive property that does not depend on the amount of substance.
