Let me explain it to you like this: Cobalt 60 is used for something called raadioisitope therapy for cancer. Uranium 238 is used to date the soil. And Carbon 14 is used for archaeologists. So the correct answer is the second one

Is the specific heat capacity of a substance an intensive or extensive property? Explain.
andre [41]

The specific heat capacity is intensive, and does not depend on the quantity.

We can categorize a property of the compound as either intensive or extensive when defining a particular aspect of it. The extent of a drug or compound is a quality that is influenced by the sample size used. However, the intense property is independent of the quantity (we can say that it is independent on the amount of the sample used). One such example of an intensive property is density.

The specific heat capacity of a substance or a compound describes the amount of heat (in Joules) needed to increase the temperature of one gram of the substance by 1 unit.

The specific heat capacity is independent on the amount of substance used, therefore, it is classified as an intensive property of a substance. The specific heat capacity will not depend on the mass of the given substance and it will be a constant value for each substance.

So the specific heat capacity is intensive, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is the same, 4.184 (J/g.K).
