Question

Discuss any two parameters which are used to characterised the Gaseous state.​

Answer 1

Parameter 1:

The Amount of Gas

The number of gas particles contained in a sample is measured in moles (n). A mole is the SI unit for the amount of matter present. One mole of substance contains an Avogadro's number of particles. The current accepted value for Avogadro's number is 6.0223 × 1023. To gain some perspective on the magnitude of it, consider a sample containing an Avogadro's number of quarters. If the quarters were spread out to cover a large city block of area one square mile, they would still have to be stacked so high that they would reach the Sun (93,000,000 miles high). For matter on the size scale of atoms or molecules, one mole of gaseous substance (under normal temperature and pressure conditions) would occupy around 12 2-liter soft-drink bottles. The proximity of particles to one another is so much greater in the other states of matter, that one mole of liquid water would occupy only one percent of one bottle- filling it roughly one centimeter.

Given the huge number of particles involved and the size of matter on the atomic or molecular scale, it is impossible to physically count out a mole of matter. Instead, the number of particles present in a sample is inferred from the mass of sample (much like jelly beans are sold by the pound instead of priced as individual candies). The molar mass of an element or compound gives the mass (in grams) of one mole of substance. For example a 12.0 g sample of Helium gas (molar mass 4.00 g/mole) contains 3.00 moles and 1.81 × 1024 gas particles:

Volume Representation

Parameter 2:

Volume

The volume of gas in a sample is measured in liters (L). The SI unit of volume, the cubic meter (m3), has magnitude that is a bit too large in consideration of the amounts and ambient conditions under which gases are normally studied. We can explore the relationship between the liter and cubic meter by examining the following conversion factors:

1 L = 1000 mL = 1000 cm3

As depicted to the left, a liter is represented by a cube with edges of ten centimeters (Volume = length × width × height = 1000 cm3). Using the fact that 1 dm (decimeter) = 10 cm:

Because 1 m = 10 dm, the liter can also be converted to the SI unit of volume:

1 L = 1 × 10 -3 m3......

Hope this helps you

Answer 2

$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$

There are four parameters which are used to characterised the Gaseous state.

• Gas Pressure
• Gas Volume
• Temperature
• No. of moles

Here, two of the parameters are discussed below :

⏭️ Gas Volume :

Due to high mobility of the gas molecules they occupy entire space available. The volume of the gas molecule is considered as volume of the container irrespective of quantity of gas taken.

⏭️ Temperature :

Temperature measures the amount of energy associate with the individual gas molecule present in a gaseous system. Gaseous system at a high temperature will have molecules with higher energy.
