What occurs when heat flows from a hotter object to a colder object?
The hotter object will get colder than it was, the colder object will get hotter than it was. Heat flow will continue until both objects are at the same temperature.
How do you heat flow between two objects?
Heat energy travels from a hotter object to a cooler/colder object until both objects reach the same temperature.
How does thermal energy move when it is near cool areas?
I am not entirely sure what you mean, but the general tendency is for heat to go from hotter object to colder objects.
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.
In what direction will heat flow between two objects with different temperatures?
From the warmer object to the colder one. page 482 in the textbook, under the soup!

Why is thermal energy equilibrium always established when two objects transfer heat?
That's because heat will naturally flow from a hotter object to a colder object - not the other way round. This will continue until both object have the same temperature.
In which direction is energy transferred as heat between two objects at different temperatures?
Heat flows from the hotter object to the colder object, unless there is some external process (such as a heat pump) which is transferring the heat in the opposite direction.
Heat always moves from what object?
From the hotter to the colder object.
According to the second law of thermodynamics which is a requirement for thermal energy to flow from colder objects to hotter objects?
The second law of thermodynamics states "energy systems have a tendency to increase their entropy rather than decrease it." This can also be stated as "heat can spontaneously flow from a higher-temperature region to a lower-temperature region, but not the other way around." Heat can appear to flow from cold to hot, for example, when a warm object is cooled in a refrigerator, but the transfer of energy is still from hot to cold. The heat from the object warms the surrounding air, which in turn heats and expands the refrigerant. The refrigerant is then compressed, expending electrical energy. so the second law of thermodynamics is your answer I believe.... there are 3 proper laws of thermodynamics with a possible fourth, fifth and sixth still being postulated.
Why is thermal energy so hard to store?
Heat has a tendency to move from hotter to colder substances. To store thermal energy, you need to keep an object hotter (or colder) than its surroundings; and there are no perfect insulators that stop the flow of heat altogether.
If there is a difference in temperature between 2 objects which way does the heat always move?
Heat will naturally flow from a hotter object to a colder object. To make it flow in the opposite direction requires some additional energy input (for example, in a refrigerator).
When objects of two different temperature are in what happens?
In that case, heat will flow from the hotter to the colder object. This will continue until both are at the same temperature.
