1.	When ethanol dissolves in water, which of the following is observed?
Answer» Absorption of heat and DECREASE in volume Absorption of heat and increase in volume Emission of heat and increase in volume Emission of heat and increase in volume Solution :NEW inter-molecular FORCESS between `C_(2)H_(5)OH` and `H_(2)O` molecules are WEAKER than the the old intermolecular FORCES between `H_(2)O-H_(2)O` molecules and `C_(2)H_(5)OH-C_(2)H_(5)OH` molecules. As such `Delta H_(max)` and `Delta V_(mix)` are both positive.
