Explain why an ice cube submerged in a drink melts faster than an ice cube on a kitchen surface (the drink, surface and room temperature are all equal). (3 marks)

(1) In the drink, all six faces are in contact with the liquid (or) On the kitchen surface, only one of the faces is in contact with a solid and the rest are in contact with the air (or) On the kitchen surface, most of the faces are in contact with the air.

(1) Liquids have a higher particle collisions than gases because particles are packed together more densely (or converse)

(1) Therefore heat transfer occurs more quickly in a liquid (or) Therefore the rate of heat transfer is greater in a liquid (strong reasoning required)
