How is it possible for a heat pump to remove thermal energy from cold objects and add it to a hotter object?

Basic trick is to make a transfer fluid that is (much) hotter than the "hotter object"
at one point in the cycle.
Heat still flows from hot to cold ... but note that the system is not overly efficient.

Does thermal energy moves?
Such energy can be transferred. Usually it will transfer from hotter objects to colder objects.
In what direction does thermal energy flow naturally?
Heat will naturally flow from hotter to colder objects.
How is thermal equilibrium established?
Thermal equilibrium is established by the transfer of heat energy from the hotter object to the cooler object until both objects are at the same temperature.
Is thermal energy ever completely convertible to mechanical energy?
No. You can only convert thermal energy to other types of energy if you have a difference of temperatures between two objects, and then you can only convert part of the thermal energy. The remainder will flow from the hotter object to the colder object.
When does thermal energy increase?
when it gets hotter
When objects get hotter what kind of energy do they have?
Thermal
Does thermal energy moves?
Such energy can be transferred. Usually it will transfer from hotter objects to colder objects.
Why is thermal energy hard to store?
Heat has a tendency to flow from hotter objects to colder objects. This can be reduced with thermal insulation, but not entirely stopped.
Is heat the transfer of thermal energy from a higher temperature to a lower temperature?
The heat transfer is possible by conduction, convection and radiation.
Why do you loose thermal energy if your body temperature is 37 degrees c and the temperature around you is 25 degrees c?
Because thermal energy travels from hotter objects to colder objects.
In what direction does thermal energy flow naturally?
Heat will naturally flow from hotter to colder objects.

Does your body gain or lose thermal energy if your body temperature is 37 degrees C and the temperature around is 25 degrees C?
Heat will naturally flow from hotter objects to colder objects. If heat flows OUT OF your body, you will LOSE that heat energy (thermal energy).
What is the energy transferred from a hotter object to a cooler one is referred to as?
This is the zeroth law of thermodynamics: objects at different temperatures will form a thermal equilibrium. The first law of thermodynamics says that energy can not be created or destroyed but can only change form. So the cooler object has to get hotter not the other way around.
When thermal energy increases?
when it gets hotter
When does thermal energy increase?
when it gets hotter
