                OBJECTIVE QUESTIONS
                 Q.1      The quantity of matter present in an object is called its:
                         (a)Weight
                         (b)Gram
                         (c)Mass
                         (d)Density
                 Q.2     When we put some crystals of potassium permanganate in a beaker
                         containing water, we observe that after sometime whole water has turned
                         pink. This is due to:
                         (a)Boiling
                         (b)Melting of potassium permanganate crystals
                         (c)Sublimation of crystals
                         (d)Diffusion
                 Q.3     The state of matter which consists of super energetic particles in the form
                         of ionized gases is called:
                         (a)Gaseous state
                         (b)Liquid state
                         (c)Bose- Einstein condensate
                         (d)Plasma state
                 Q.4     When a teaspoon of solid sugar is dissolved in a glass of liquid water, what
                         phase or phases are present after mixing:
                         (a)Liquid only
                         (b)Still solid and liquid
                         (c)Solid only
                         (d)None of these
                 Q.5     Non- reacting gases have a tendency to mix with each other. This
                         phenomenon is known as:
                         (a)Chemical reaction
                         (b)Diffusion
                         (c)Effusion
                         (d)Explosion
                 Q.6     Select the one that is not a matter:
                         (a)Feeling of hot
                         (b)Smoke
                         (c)Humidity
                         (d)Water
                 Q.7     . Zig-zag movement of the solute particle in a solution is known as
                         (a) Linear motion
                         (b) Circular motion
                         (c) Brownian motion
                         (d) Curved motion.
