SUMMARY

• Kinetic theory of matter, Properties of solids, liquids and gases, Force of cohesion and adhesion
• Surface Tension, Heat transfer in solids, liquids, and gases

SECTION I – OBJECTIVE

1. Anything that occupies space and has mass is called
   1. Matter
   2. Cohesion
   3. Adhesion
   4. None of these
2. The intermolecular space is maximum in case of
   1. Liquids
   2. Solids
   3. Gases
   4. None of these
3. The molecules can move freely anywhere in
   1. Gases
   2. Liquids
   3. Solids
   4. None of these
4. The molecules do not move within the boundary of:
   1. Liquids
   2. Gases
   3. region
   4. None of these
5. After absorbing heat, the molecules moves from the hot region to the cold region due to
   1. Conduction
   2. Convection
   3. Radiation
   4. None of these
6. After absorbing heat, the molecules vibrate more frequently about their mean position and transfer their energy to the surrounding molecules in case of:
   1. Convection
   2. Conduction
   3. Absorption
   4. None of these
7. The inter molecular forces in liquids are
   1. Less than in gases
   2. More than in solids
   3. Same as in solids
   4. Less than in solids
8. The force of attraction between the molecules of similar kinds is defined as the force of
   1. cohesion
   2. adhesion
   3. surface tension
   4. none of these

SECTION II - SUBJECTIVE

1. Differentiate between the force of cohesion and force of adhesion. Give one example of each.
2. Define :
   1. Matter
   2. intermolecular space
   3. surface tension
3. Give any two properties of :
   1. Solids
   2. liquids
   3. gases
4. Explain the surface tension in liquids, with reasons.
5. Water wets a glass surface whereas mercury does not wet it. Explain.
6. Discuss the transfer of heat by :
   1. conduction
   2. convection
