ASSERTION AND REASON DIRECTION : In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as: (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A). (b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A). (c) Assertion (A) is true but reason (R) is false. (d) Assertion (A) is false but reason (R) is true. Questions: 1. Assertion : Camphor disappears without leaving any residue. Reason : Camphor undergoes sublimation. (1 Point) Option a Option b Option c Option d 2. Assertion : Liquids diffuse easily as compared to gases. Reason : Inter molecular forces are greater in liquids. (1 Point) Option a Option b Option c Option d 3.Assertion : There is no change in the temperature of a substance when it undergoes a change of state through it is still being heated. Reason : The heat supplied is absorbed either as latent heat of fusion or as latent heat of vaporization. (1 Point) Option a Option b Option c Option d 4.Assertion : During evaporation of liquids, the temperature remains unaffected. Reason : Kinetic energy of the molecules is directly proportional to temperature. (1 Point) Option a Option b Option c Option d 5.Assertion : It is easier to cook food at high altitudes. Reason : The boiling point of water decreases at high altitudes. (1 Point) Option a Option b Option c Option d 6.Assertion : A gas can be easily compressed by applying pressure. Reason : Since the inter-particle spaces in the gaseous state are very small, they cannot be decreased by applying pressure. (1 Point) Option a Option b Option c Option d 7.Assertion : The inter molecular forces in solid state are stronger than those in the liquid state. Reason : The space between the particles of matter is called inter molecular space. (1 Point) Option a Option b Option c Option d 8.Assertion : When a beam of light is passed through a colloidal solution placed in a dark place the path of the beam becomes visible. Reason : Light gets scattered by the colloidal particles. (1 Point) Option a Option b Option c Option d 9.Assertion : A solution of table salt in a glass of water is homogeneous. Reason : A solution having different composition throughout is homogeneous. (1 Point) Option a Option b Option c Option d 10.Assertion : A true solution do not exhibits Tyndall effect. Reason : A true solution is a heterogeneous mixture. Immersive Reader (1 Point) Option a Option b Option c Option d
