It's the heat energy.
"The energy can neither be created or nor destroyed but can be transformed from one form to another".
If one system is with higher temperature and if another system of lower temperature is placed, the temperature gradually moves from higher to lower.

Thermal energy that flows from a higher temperature to a lower temperature is called heat. Heat is energy that flows from one object to another, because of a temperature difference.
When a hotter/colder object touches the opposite heat of it, then the colder ones thermal energy will go up and the hotter ones thermal energy will go down until then have then same temperature.the cold air is pushed down and the hot air forced up.Answer'Heat' is defined as energy in transit from a higher temperature to a lower temperature.
Thermal energy always flows from higher temperature to lower temperature. This is the nature of heat.
All thermal energy flows from high temperature objects to low temperature objects. This is the nature of thermal energy.
Higher temperature to lower temperature. Thermal energy will always flow down the energy gradient.
Heat.
The temperature of an object affects how much heat can be transferred. This is because if the object to which heat is transferred has high temperature then there will not be much heat transfer. Heat flows from a body of higher temperature to lower temperature.
im pretty sure its heat. im not sure but that is what i remember it as.
Temperature decreases.
