It will flow to the cold substance
Assuming that 'cold' means normal room temperature, then heat would flow from your finger to the water.
Water droplets will start evaporating on contacting the pan bottom, and they will tend to "dance" on the produced steam.
The California current carries cold water to the south.
It is a matter of density cold water is denser(compact) that hot water. thus cold water will flow faster than less dense(loose)hot water.
Heat flows towards cold.
direction of flow
Cold currents generally flow towards the equator. (a.k.a. south).
Yes, at the surface but the full Gulf Stream is a cycle. It includes a flow of cold water in the opposite direction and which travels at depth.
No, its to cold
Warm or cold defines the temperature of the water. In general warm currents flow north and cold currents flow south. That makes sense. Also warm currents flow on the surface and cold currents flow deep since cold water is denser than warm water.
Where the ground water leakage direction meet into the surface water is called Base flow.
