  1. 2. a process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane
  2. 6. energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. It is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state
  3. 8. the energy which a body possesses by virtue of being in motion.
  4. 12. it refers to the attractive forces between unlike substance, such as mechanical forces (sticking together) and electrostatic forces (attraction due to opposing charges). In the case of a liquid wetting agent, this causes the liquid to cling to the surface on which it rests.
  5. 14. a mixture in which the composition is uniform throughout the mixture.

  1. 1. it may be defined as an electrically neutral medium of positive and negative particles. It is one of the most commonly occurring states of matter in universe. It occurs naturally in the stars.
  2. 3. In 1920, this Indian physicist had done some calculations for a fifth state of matter. Building on his calculations, Albert Einstein predicted a new state of matter
  3. 4. it is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage
  4. 5. a mixture with a non-uniform composition
  5. 7. it is a generic term for the collective intermolecular forces responsible for the bulk property of liquids resisting separation. Specifically, these attractive forces exist between molecules of the same substance.
  6. 9. this law states that the total pressure by a mixture of gases is equal to the sum of the partial pressures of each of the constituent gases
  7. 10. it is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
  8. 11. it is the change of gaseous state directly to solid state without going through liquid state.
  9. 13. it is the movement of a substance from an area of high concentration to an area of low concentration. this process happens in liquids and gases because their particles move randomly from place to place
