It's not an energy transfer. It creates a convection current though.

Does it take less energy to heat hotter water than colder water?
Yes, as the molecules of the hot water are already in motion, they need less energy to speed up and transfer it whereas the molecules of cold water need far more energy so that they get into motion and then transfer energy.
When warm air rises cold air will what?
The cold air will sink.
How does drops of water get on a cold glass?
Its condensation
Hot air rises cold air sink?
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
What is conduction covection and radiation?
Conduction is when heat is transferred through a material by passing thermal energy from molecule to molecule (from collisions). An example is when you heat up one end of a pan and the handle gets hot a little later. Convection is when, as they say, heat rises. This applies to liquids and gases because their molecules are mobile. The hot molecules still stay hot, same with the cold ones, but they rearrange themselves so heat flows. One example is, as said before, hot air rises and cold air sinks. Finally, radiation is a transfer of energy via electromagnetic radiation (light waves). This is how the sun heats stuff on the Earth.
What is heat transfer when hot air rises and cold air sinks?
Convection...
What is the transfer of heat when warm material rises and cold sinks?
This is called convection.
Does hot and cold water mix with food coloring when hot water rises to the top?
I think not because cold water is heaver than hot water and hot water rises to the top and cold drops to the bottom.
How can heat energy transfer from hot body to cold body?
Modes for heat transfer are:convection (the air around a warm object gets hot and rises)conduction(direct contact)radiation(like the heat you feel from the sun)
How does convection transfer?
Think of a pot of boiling water. The burner makes the heat, the heat rises, and the cold water replaces it, then the cold water gets hotter and rises. It's a cycle

Which is less dense cold air or cold water?
cold air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.
How does energy from heat transfer from a hot source to a cold source?
Convection
How does energy transfer?
hot to cold, fast to slow, high to low.
Does aluminum conduct cold faster than glass?
Aluminum is a conductor and glass is an insulator. Conductors allow the flow of energy transfer, but insulators block this transfer of energy. So by definition, Yes, aluminum conducts cold or heat(energy) transfer faster than glass.
