Document Summary
The better the intermolecular forces between the solute and solvent, the more it will dissolve. The stronger the forces of the solute, the less it will dissolve. Like dissolves likes - solutes will dissolve in solvents w similar intermolecular forces. Different for alcohols (oh group) miscible- involving liquids soluble-involving gasses and solids. *anytime 2 things come together energy is released. Energy released when to gasses come together to form a solid. Depends on ionic charge & ionic radius. Breaking of these reactions between the water, and the water becoming attracted to the ions. Sum of enthalpy changes associated w formation of ionic solid from constituent elements. When dissolving something that absorbs heat, the temperature of the water will decrease. Surface area= bathtub will have more evaporation than a glass of water. Intermolecular forces=the faster the kinetic energy of the molecules, and weaker the forces, the easier it is for them to become gaseous particles (stronger imf decreases evaporation)
