               Subjective Questions:-

               Q.                                 Questions                               Skill    Marks
               No.
               1.       By which process can you pour the clear liquid without            R        1
                        disturbing the sediments?

               2.       How can you converta vapour into the liquid state?                U        1

               3.       DIRECTION:  Each  of  these  questions  contains  an  U                    1
                        Assertion followed by Reason. Read                them
                               carefully and answer the question on the basis
                        of following options. You have to select the  one           that
                        best describes the two statements.
                           a)  If  both  Assertion  and  Reason  are  correct  and
                               Reason is the correct explanation of Assertion.
                           b)  If  both  Assertion  and  Reason  are  correct,  but
                               Reason  is  not  the  correct  explanation  of
                               Assertion.
                           c)  If Assertion is correct but Reason is incorrect.
                           d)  If Assertion is incorrect but Reason is correct.
                           e)  If Assertion & Reason both are incorrect.
                        Assertion(A): The fine suspended particles in water can be
                        separated using alum.
                        Reason(R): Alum makes the fine suspended particles heavy
                        and they settle down faster.
               4.       You have a mixture of fine sand and water. You are given a        U&A      3
                        filter paper to separate the components.
                           (a) Name the process you will use to separate sand from
                               water?
                           (b) What is residue?
                           (c) What is filtrate?
               5.       Suggest a suitable method to separate the components of           HOT      5
                        the following mixtures:
                           a.  A mixture of chalk and water
                           b.  Salt from sea water


                                                                                                            2
