11th Chemistry Weekly Test - 4 ( Gaseous State )-Aug 2020

Time : 1.30 Hours

Part - A

Generic 3 - Answer All Question

Show how the molar volume of a real and ideal gas are related to each other?

What are the consequences of Boyle's law?

8 g of methane is placed in a 5 litre container at 27° C. Find Boyle's constant.

Mention different methods of liquefaction of gases

Give suitable explanation for the following facts about gases.
(a) Gases don't settle at the bottom of a container.
(b) Gases diffuse through all the space available to them

Explain the graphical representation of Charles' law.

Using Andrew's isotherm of CO₂ explain the terms (i) critical temperature, (ii) critical pressure and (iii) critical volume.

A combustible gas is stored in a metal tank at a pressure of 2.98 atm at 25°C. The tank can withstand a maximum pressure of 12 atm after which it will explode. The building in which the tank has been stored catches fire. Now predict whether the tank will blow up first or start melting? (Melting point of the metal = 1100 K).

Explain Charles' law with an experimental illustration.

Of two samples of nitrogen gas, sample A contains 1.5 moles of nitrogen in a vessel of volume of 37.6 dm³ at 298K, and the sample B is in a vessel of volume 16.5 dm³ at 298K. Calculate the number of moles in sample B.
