1 ) The internal energy of fixed mass of an ideal gas depends on ………………..
A ) Pressure , b ) Volume ,
C ) Temperature , d ) All of these ,
Correct answer : - C ) Temperature ,
( It depends on temperature , not on pressure and its volume ) .
2 ) The boiling point of noble gas increases ………….. And noble gases has very low boiling point as compare to others .
A ) Down the group . b ) Going up the group ,
C ) Both , d ) None of these ,
Correct answer : - A ) Down the group .
3 ) Colligative properties depend on …………
A ) Solute , b ) Solvent ,
C ) Both , d ) None of these ,
Correct answer : - A ) Solute ,
( It depends Solute particles not in nature of solute ) .
4 ) Relation between kw, ka, kb is …………….
Correct answer : - ( kw = ka * kb ) .
5 ) Buffer solution resist ………….. when small amount of a strong acid or base is added.
A ) Change in PH , b ) Does not change in PH ,
C ) Both , d ) None of these ,
Correct answer : - A ) Change in PH ,
6 ) Water (H2O) has…………….. than HF. Because HF forms 1 hydrogen bond and H2O forms 2 hydrogen bond. More hydrogen bonds, higher B.P.
A ) Higher boiling point , b ) Higher melting point ,
C ) Both , d ) None of these ,
