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.

What is the study of relationships between heat work and thermal energy?
Thermodynamics is the study of the relationship between thermal energy and heat and work.
Which law of thermodynamics is the conservation of energy applied to thermal systems?
Conservation of energy is the 1st law of thermodynamics.
Do hotter objects emit photons with a shorter wavelength?
Yes, according to the laws of thermal radiation.
The study of conversions between thermal energy and other forms of energy?
thermodynamics
What is the transfer of thermal energy from warmer regions to cooler regions?
the second law of thermodynamics
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.
Different between thermal and thermodynamics?
Thermal is an adjective, meaning to do with heat. Thermodynamics is a noun, a branch of physics to do with the thermal properties of materials, and has several laws which are the basis of design of heat engines and other thermal processes.
What is the study of relationships between heat work and thermal energy?

What are variables for the first law of thermodynamics?
the internal energy (thermal energy)
Do hotter objects emit photons with a shorter wavelength?

What is it called when solids are heated?
Thermal expansion in accordance with the first law of thermodynamics.
The study of conversions between thermal energy and other forms of energy?
thermodynamics
Does wind have thermal energy?
yes. everything has some thermal energy. Even liquid nitrogen has some thermal energy. Nothing can have no thermal energy, look at the 3rd law of thermodynamics.
What is the transfer of thermal energy from warmer regions to cooler regions?
the second law of thermodynamics
Is there a change in an objects thermal energy if the object is at thermal equilibrium?
no
