1 ) Air at sea level is dense . This is a practical application of . . . . . . . . . ,

A ) Charle's law .                                       B ) Dalton's law .

C ) Boyle's law .                                        D ) None of these ,

Correct Answer : -   C ) Boyle's law .

Boyle's law : -

V ∝ 1 / P .

 

2 ) An ideal gas obeying kinetic gas equation . . . . . . . . . . . . be liquefied .

A ) can ,                                                     B ) cannot ,

C ) may or may not ,                                 D ) None of these ,

Correct Answer : -   B ) cannot ,

Ideal gas cannot be liquefied at any value of P and T .

 

3 ) The temperature below which a gas does not exist is called . . . . . . . . . ,

A ) critical temperature ,                           B ) absolute temperature ,

C ) None of these ,

Correct Answer : -   A ) critical temperature ,

 

4 ) For an ideal gas , no. of moles per litre in term of its pressure P , gas constant R and temperature T is : -

P V = n R T .

So ,  n / V  =  P / RT .

 

5 ) Equal volume of gases at same temperature and pressure contains equal number of particles . This statement is direct consequence of ideal gas equation .

P V = n R T .

 

6 ) Distillation means to purify liquid by boiling .

 

7 ) Absolute temperature is the temperature at which all molecular motion breakouts .

 

8 ) Triple point of water is . . . . . . . . . . . ,

A ) 0 k° .                                                     B ) 273 k° ,

C ) 300 k° .                                                          D ) All of these ,

Correct Answer : -   B ) 273 k° ,
