Why is heat capacity an extensive property, while the specific heat capacity and molar heat capacity are intensive properties?

Specific heat capacity and molar heat capacity are the heat required to raise the temperature of "1 gram" and "1 mole," respectively, by 1 degree Celsius. In contrast, heat capacity is the heat required to raise the temperature of "an object" by 1 degree Celsius. Dividing by the amount of substance present (as with specific heat and molar heat capacities) makes it an intensive property. Heat capacity remains an extensive property because it depends on the amount of substance.
