Assertion (A):Air is everywhere but we cannot see it.

                     Reasoning(R): Air is colourless, odourless gas.


         Q.3         How can you show that air occupies space?                                 3          R+A
         Q.4         Mention three properties of air.                                          3          R + U

         Q.5                                                                                   5          HOT
                     An empty glass is immersed into water kept in a tub in the
                     following manner

                        a)  Upside down.
                        b)  By bending the glass.
                     Write the observation in both a) and b)

                     Conclude your inferences in both cases.

                     If we take a glass with half-filled water, what will be our
                     observation?
