When ammonium nitrate (NH4NO3) dissolves in water, the solution feels cool. Which statements are true? Select all that apply. The process is endothermic. The attractive forces between solvent and solute particles are weaker than between the particles in the pure substances. The process is exothermic. The attractive forces between solvent and solute particles are stronger than between the particles in the pure substances.

There are a smallpackage of ammonium nitrate (NH4NO3) in water. When the inside bag is broken, the solute dissolves in the water. This dissolution requires energy and the water cools and freezes. I have done many experiments to find the best packs, and the market leader uses 300 g of the solute and 300 mL of water. It reaches a final temperature of -2 C. If I assume the dissolution processis so fast that it can be modelled as adiabatic,...
