Question

Name four measurable properties of gases.

Answer 1

Hint: Gases have many measurable and non-measurable properties. Gases have less intermolecular forces comparison to solid and liquids. They occupy the volume of the container in which they are kept. Hence, gases can be measured on the basis of their properties


Complete solution:
Measurable properties are those properties which can be measured by any physical or chemical experiment. In measurement it is measured against a standard unit to find the amount of that property.
Here is a brief description about the measurable properties of gases.
1. Mass : every gas has mass generally we measure mass of gases in moles every gas has a different mass indefinite mole example one mole of $C{O_2}$ weighs 44 gram we can easily measure mass of gases by beam balance method units of mass 6 kg gram and the SI unit of mass is kg.
2. Volume : Volume is a very important properties of gases which is widely used in science. Gases don't have definite volume they occupy entire volume of vessel in which they are kept. Some units of volume is $c{m^3}$ , ${m^3}$ , liter and millimeter. SI unit of volume is ${m^3}$ .
3. Temperature : Temperature of a gas is a property that tells about the hotness and coldness of the gases. Internal energy of gas depend upon only temperature. Some units of temperature are degree Celsius Fahrenheit and Kelvin. SI unit of temperature is Kelvin. We can measure the temperature of a gas by gas thermometer.
4. Pressure : Pressure of a gas is force exerted by a gas on the walls of the container in per unit area. We can measure the pressure of a gas by using barometer. Some units of pressure are $dyne{\text{ }}{m^{ - 2}}$ , $N{m^{ - 2}}$ , atm and Pascal. SI unit of pressure is $N{m^{ - 2}}$ .


Note:Gases have many measurable properties. These measurable properties of a gas are dependent to each other by ideal gas equation given by
$PV = nRT$
Where P = Pressure of the gas
V = volume of the gas
n = number of moles of gas
R = gas constant
T = Temperature of the gas
 It shows the relation between the properties of gas. Gas doesn't have a definite shape and definite volume. Intermolecular forces in gas are negligible.
