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).

Elis [28]

First we need to calculate the number of moles of FeS_{2}:

number of moles = mass (grams) / molecular mass (g/mol)

number of moles of FeS_{2} = 198.2/120 = 1.65 moles

From the chemical reaction we deduce that:

if            4 moles of FeS_{2} produces 8 moles of SO_{2}

then  1.65 moles of FeS_{2} produces X moles of SO_{2}

X = (1.65×8)/4 = 3.3 moles of SO_{2}

Now we can calculate the mass of SO_{2}:

mass (grams) = number of moles × molecular mass (grams/mole)

mass of SO_{2} = 3.3×64 = 211.2 g
