Final answer:
Heat is an extensive physical property because its value is proportional to the amount of substance present. The correct answer to the student's question is D) extensive physical property.
Step-by-step explanation:
Heat is a type of property that depends on the amount of matter present. Therefore, it is classified as an extensive property, and since it pertains to energy transferred rather than matter transformed, it is a physical property, not a chemical one. We can see this by considering scenarios such as heating up different amounts of a substance; the total amount of heat energy will vary depending on the mass, even though the temperature might be the same. This defines heat as an extensive physical property.
To answer the student's question: Heat is a) an intensive physical property, b) an intensive chemical property, c) an extensive chemical property, or d) an extensive physical property. The correct choice is D) extensive physical property.
