States of Matter: Assignment (3 Marks Each)

The document is an assignment from www.tiwariacademy.net on the topic of states of matter. It contains 6 questions about gas laws, ideal gas behavior, gas mixtures, and calculating total pressure. The questions cover explaining phenomena related to evaporation and atmospheric gas layers, deriving the ideal gas equation, comparing differences between solids, liquids and gases, and calculating pressures for gas mixtures and ideal gases using the ideal gas law.

States of Matter
Assignment ( 3 marks each )

1. Account for the following :


(a) Cooling is always caused during evaporation.
(b) Carbon dioxide is heavier than oxygen and nitrogen but it does not form
the lower layer of the atmosphere.
(c) Gases like CO2 and CH4 show more deviation from the ideal gas behaviour
as compared to gases like H2 and He.
2. With the help of gas laws, deduce an expression for the ideal gas equation. What
is the utility of the gas equation ?
3. List the three main points of difference between a solid, a liquid and a gas.
4. What will be the pressure of the gas mixture when 0.5 L of H2 at 0.8 bar and
2.0 L of oxygen at 0.7 bar are introduced in a 1 L vessel at 27º C ?
5. Pressure of 10 g of an ideal gas ‘A’ at 27º C is found to be 2 bar. When 20 g
of another ideal gas ‘B’ is introduced in the same flask at same temperature,
the pressure becomes 3 bar. Find the relationship between their molecular
masses. [Ans. MB = 4MA]
6. Calculate the total pressure in a mixture of 8.0 g of oxygen and 4.0 g of
hydrogen confined in a vessel of 1 dm3 at 27º C. R = 0.083 bar dm3 K−1 mol−1.
[Ans. 56.025 bar]
