Test: Gaseous State - Question 1

The gaseous state is characterized by the sensitivity of volume change with the change of pressure and temperature due to:

Detailed Solution for Test: Gaseous State - Question 1
The gaseous state is characterized by the large distance between molecules as compared to their own dimensions. This leads to the sensitivity of volume change with changes in pressure and temperature.
Test: Gaseous State - Question 2

The degree of hotness or coldness of a body is measured by temperature. What is the correct relation between Celsius (C), Kelvin (K), and Fahrenheit (F) scales?

Test: Gaseous State - Question 3

Which unit is used for pressure in the SI system?

Detailed Solution for Test: Gaseous State - Question 3

In the SI system, pressure is measured in Pascals (Pa).

Test: Gaseous State - Question 4

Density is defined as mass per unit volume. What is the correct relation between CGS and SI units for density?

Test: Gaseous State - Question 5

What is the ideal gas equation that relates pressure (P), volume (V), number of moles (n), and temperature (T) for a gas?

Detailed Solution for Test: Gaseous State - Question 5

The ideal gas equation that relates pressure (P), volume (V), number of moles (n), and temperature (T) for a gas is PV = nRT

Test: Gaseous State - Question 6

What is the correct numerical value of the universal gas constant (R) in liter atmosphere per degree mole?

Test: Gaseous State - Question 7

What is the correct equation to calculate the relative density (vapour density) of a gas with respect to hydrogen?

Test: Gaseous State - Question 8

According to Dalton's Law of Partial Pressure, what is the relationship between total pressure (PT) and partial pressures (P1, P2, ...) of gases in a mixture?

Detailed Solution for Test: Gaseous State - Question 8

Explanation of Dalton's Law of Partial Pressure:
 


  • Dalton's Law of Partial Pressure states that in a mixture of gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases present.

  • This means that the total pressure (PT) of a mixture of gases is equal to the sum of the partial pressures (P1, P2, etc.) of each gas in the mixture.

  • Mathematically, this relationship can be expressed as PT = P1 + P2 + ...

  • Each gas in the mixture exerts a partial pressure that contributes to the total pressure of the system.

  • This law is based on the assumption that the gases in the mixture do not chemically react with each other and behave independently.

Test: Gaseous State - Question 9

What does Graham's Law of Diffusion state?

Detailed Solution for Test: Gaseous State - Question 9

Graham's Law of Diffusion states that the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass.

Test: Gaseous State - Question 10

A gaseous mixture contains 60% nitrogen (N2), 25% oxygen (O2), and 15% carbon dioxide (CO2) by mass at a total pressure of 1.2 atm. Calculate the partial pressure of each gas.

Detailed Solution for Test: Gaseous State - Question 10

Mole fraction of each gas:

Partial pressures:
