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.
What else can I help you with?
What is a condition where all objects in a system are at the same temperature?
When all objects in a system are at the same temperature, they are said to be in thermal equilibrium. This means that there is no net transfer of heat energy between the objects, and their temperatures are equalized. Thermal equilibrium is a key principle of thermodynamics.
Why does thermal energy only move from the warmer object to the cooler object?
Thermal energy moves from warmer objects to cooler objects because of the second law of thermodynamics, which states that heat naturally flows from a higher temperature to a lower temperature until thermal equilibrium is reached. This is due to the tendency of molecules to seek a state of equilibrium and distribute their thermal energy evenly.
What energy always moves from warmer objects to colder objects?
Heat energy always moves from warmer objects to colder objects, following the principle of the second law of thermodynamics. This transfer of heat occurs until thermal equilibrium is reached between the objects.
Can thermal energy flow from cooler objects to warmer objects?
No, thermal energy typically flows from warmer objects to cooler objects due to the difference in temperature. This is governed by the second law of thermodynamics, which states that heat naturally flows from areas of higher temperature to areas of lower temperature in order to reach thermal equilibrium.
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.

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.
What energy always moves from warmer objects to colder objects?
Heat energy always moves from warmer objects to colder objects, following the principle of the second law of thermodynamics. This transfer of heat occurs until thermal equilibrium is reached between the objects.
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.
Can thermal energy flow from cooler objects to warmer objects?
No, thermal energy typically flows from warmer objects to cooler objects due to the difference in temperature. This is governed by the second law of thermodynamics, which states that heat naturally flows from areas of higher temperature to areas of lower temperature in order to reach thermal equilibrium.
What is the transfer of thermal energy by electromagnetic waves?
Thermodynamics
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.
Why does heat travel from hot object to cold?
Heat travels from hot objects to cold objects because of the fundamental principle of thermodynamics known as the second law of thermodynamics. This law states that heat naturally flows from areas of higher temperature to areas of lower temperature in order to achieve thermal equilibrium, where both objects eventually reach the same temperature.
Is thermal energy transferred from warmer to cooler or cooler to warmer?
Thermal energy is transferred from warmer objects to cooler objects. This is based on the fundamental principle of the second law of thermodynamics, which states that heat naturally flows from higher temperature regions to lower temperature regions.
Which law of thermodynamics is the conservation of energy applied to thermal systems?
The first law of thermodynamics is the conservation of energy applied to thermal systems, stating that energy cannot be created or destroyed, only transferred or transformed in a system.
What are variables for the first law of thermodynamics?
the internal energy (thermal energy)
