It is true incase of heat energy. Take a rod and heat it at one end after sometime other end also becomes hot --means heat energy flows by conduction/convection.

Heat :)
In thermodynamics, heat is defined as the energy in transfer between a system and its surroundings. In practice we consider the flow from the higher energy state to the lower energy state. In the case of thermal energy, from the body with the higher thermal energy (warmer) to the body with the lower thermal energy (cooler). In general, however, you may define the flow in either direction you wish, though if you define it as from cooler to warmer, the magnitude would be negative.
We call the flow of thermal energy from warmer matter to cooler matter heat transfer, and we study this in thermodynamics. A link can be found below to check facts and learn more.
Thermodynamics, which means, basically, "heat movement".
energy alwayy flow from high density to low density
yes the heat will flow threw, but not create energy
because thermal energy always flows from warmer matter to cooler matter

Heat is thermal energy. If two objects having different temperatures are brought into contact, heat will always flow from the warmer one to the cooler one, until their temperatures are equal.
It must flow out, ice contains less energy than water. You just have to remember that heat is energy, and all energy, no matter what form, eventually winds up as heat. Take heat energy out of water, it gets cooler, and eventually freezes. Add heat energy to ice, it first changes state to liquid, and then starts to get warmer. Keep adding heat energy to it, it keeps getting warmer and warmer. Keep additing heat energy to it, and eventually it changes state to gas ... called "steam". Take heat energy out of the steam, it first changes state to liquid, then gets cooler. etc. etc.
Molecules
from cooler to warmer surfaces
The flow of heat energy from the warmer object to the cooler oneis so probable that it is considered a law in thermodynamics.
