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).

How does freezing affect the volume of water?
MrRissso [65]

Increases the volume of water

Explanation:

Freezing of water causes the volume of water to increase by a whooping 4%. This is why the density of water is slightly different that of ice.

When ice freezes it expands and takes up more volume of space for the same mass given.

This is why bottles break when water in them is frozen.

This increase in volume is why ice floats on water. It makes it less dense.

Gasoline has a density of .74g/mL. How many milliliter if gasoline have a mass of 2.5kg?
nata0808 [166]

Answer: 3378.4mL

Explanation:

density of Gasoline = 0.74g/mL.

Volume of gasoline in milliliter = ?

mass of gasoline = 2.5kg

(Since density is in grams per millilitre, convert mass in kilograms to grams)

If 1kg = 1000grams

2.5kg = 2.5 x 1000 = 2500grams

Recall that density is obtained by dividing the mass of a substance by its volume

i.e Density = Mass / Volume

0.74g/mL = 2500grams/Volume

Volume = (2500 grams / 0.74g/mL)

Volume = 3378.4mL

Thus, the volume of gasoline is 3378.4mL
