Question

How is heat energy transferred from water in one calorimeter to the water of the other one?

Answer 1

I believe you are asking the wrong question.  A calorimeter is a measuring device.  It does not transfer from any material only measures.

Answer 2

Heat is energy. Based on the law of conservation of energy, it cannot be destroyed nor be created but transformed or change into a different form of energy. This heat energy can be converted into kinetic energy ( energy of motion). The movement of the particles colliding with the particles of another material caused energy to be transferred. In short, heat energy is transferred from hot objects to cold objects. In the case of water, if both liquids are in the same container, then the mode of heat transfer is convection. If they are in separate containers and the containers are touching one another or there is a heat conductor betweem them, then the mode of heat transfer is conduction.
