When liquid A is mixed with liquid B, the temperаture decreаses. Which оf the fоllоwing stаtements are correct about this mixing process? Interactions between molecules of liquid A and molecules of liquid B are weaker than the interactions formed between liquid A and liquid B when mixed. Interactions between molecules of liquid A and molecules of liquid B are stronger than the interactions formed between liquid A and liquid B when mixed. The solution (formed after mixing) has higher entropy than pure solute and pure solvent because more arrangements are possible. The solution (formed after mixing) has lower entropy than pure solute and pure solvent because less arrangements are possible. Liquid A is miscible with liquid B. Liquid A is immiscible with liquid B.
