Q.8     Which is incorrect statement:
                         (a)Matter is continuous in nature.
                         (b)Of the three state of matter, the one that is most compact is solid state.
                         (c)In solid state inter-particles space (i.e., empty space) is minimum.
                         (d)The density of solid is generally more than that of a liquid.
                 Q.9     When a gas jar full of air is placed upside down on a gas jar full of bromine
                         vapours, the red-brown vapours of bromine from the lower jar go upward
                         into the jar containing air. In this experiment:
                         (a) Air is heavier than bromine
                         (b) Both air and bromine have the same density
                         (c) Bromine is heavier than air
                         (d) Bromine cannot be heavier than air because it is going upwards
                         against gravity

                 Q.10    .  Which of the following cannot be considered a form of matter?
                         (a) Atom
                         (b) Water
                         (c) Love
                         (d) Electron

                 Q.2     Explain the diffusion of copper sulphate into water.
                 Q.3     Describe why a drop of food coloring in a glass of water slowly becomes evenly
                         distributed without the need for stirring?
                 Q.4     Give reasons
                             a)  Liquid mix more slowly than gases. Why?
                             b)  The smell from agarbatti can travel a longer distance.
                 Q.5     The particles of matter are extremely small. Explain with an activity.
