When we place a water bottle with cold water on top of a water bottle with hot water the particles in the hot water bottle rise, pushing the cool particles to the bottom. This is a type of heat transfer called convection. Basically, the hot particles in the hot water bottle rise to the cold water bottle at the top and the cool particles in the cold water bottle at the top sink to the hot water bottle at the bottom. This is one of the three heat transfers. Convection occurs in gases and liquid.
