Bottled soft drinks get cooled, more ............. by the ice cubes than by the iced water, both at 0∘C ?
Answer is A
Every 1 kg of ice at 0oC absorbs 336000J of heat energy to form water at 0oC .An ice can extract 336000 J of heat, more than water at 0oC ,therefore it cools the bottled drink more effectively.
