The only difference is the polarity(physical property) The Cis - polar compound while Trans-1, -di chloroethane is non polar (2bi) (i) Temperature remains constant during boiling (ii) There is change of state during boiling (2bii) I - It will increase the boiling point of water. II - It will reduce the boiling point of water. (2biii) Boiling occurs at a specific temperature While Evaporation occurs at almost all temperatures. (2ci) An unsaturated solution is one that contains less than the maximum amount of solute that can dissolve at a given temperature While A saturated solution is one that contains maximum of solute that can be dissolved in it at that temperature. (2cii) (i) By increasing the temperature of the solution. (ii) By increasing the amount of the solute. (2ciii) Temperature. (2di) Mole i
