Final answer:
Specific heat capacity is the intensive physical property of matter among the given options as it does not depend on the amount of matter present. Mass and volume are extensive, while flammability and reactivity are chemical properties.
Step-by-step explanation:
The question at hand is asking to identify an intensive physical property of matter from a list of options. In science, particularly Chemistry, intensive properties are those that do not depend on the amount of matter present. For example, temperature and density are both intensive properties. The options provided include specific heat capacity, flammability, mass, volume, and reactivity.
Out of these options, specific heat capacity is an intensive physical property. Specific heat capacity refers to the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius and is independent of the sample's mass or volume. Therefore, specific heat capacity meets the criteria for an intensive property.
On the other hand, properties such as mass and volume are extensive properties because they change with the amount of the substance. Flammability and reactivity are chemical properties because they describe the behavior of a substance during a chemical reaction.
