Heat will flow naturally from hotter objects to colder objects. To flow the other way, from colder objects to hotter objects, requires energy to be used.

What law of thermodynamics does this illustrates when two objects are in thermal equilibrium?
When two objects are in thermal equilibrium, not heat will flow between them - which is in accord with the 2nd law of thermodynamics. This is also related to (but different from) the zeroeth law which states that if two objects are each in equilibrium with a third object, they must be in thermal equilibrium with each other.
Zeroth law of thermodynamics in short?
If A,B and C are three systems and A is in thermal equilibrium with B and B is in thermal equilibrium with C then according to zeroth law of thermodynamics C is in thermal equilibrium with A.
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.
Is it true or false that according to the second law of thermodynamics the thermal energy of a system changes when work is done on the system?
What you describe is actually a consequence of the FIRST law of thermodynamics.
What is thermal equlibrium-?
Thermal equilibrium is the subject of the Zeroth Law of Thermodynamics. Zeroth Law of Thermodynamics. The "zeroth law" states that if two systems are at the same time in thermal equilibrium with a third system, they are in thermal equilibrium with each other.
Which law of thermodynamics is the conservation of energy applied to thermal systems?
Conservation of energy is the 1st law of thermodynamics.
What is the name of thermal energy that moves from high tepmerature objects to low trmperature objects?
All thermal energy flows from high temperature objects to low temperature objects. This is the nature of thermal energy.
What are variables for the first law of thermodynamics?
the internal energy (thermal energy)
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.
Thermal energy flows from what object to what object?
Thermal energy flows from warmer objects to colder objects.
What is it called when solids are heated?
Thermal expansion in accordance with the first law of thermodynamics.
What is the study of the relationship between thermal energy and heat and work?
Thermodynamics is the study of the relationship between thermal energy and heat and work.
Energy transferred from a hotter object to a cooler one is called?
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 is the transfer of thermal energy from warmer regions to cooler regions?
the second law of thermodynamics
Does two objects at different temperature have same thermal energy explain?
No,two objects at different temperature does not have the same thermal energy because both objects have different temperature .object with high temperature has more thermal energy and the object with low temperature has less thermal energy.
What is the study of energy and its ability to change matter?
For thermal energy, thermodynamics. For energy of movement, mechanics.
The flow of thermal energy from warmer to cooler substances is?
Thermodynamics, which means, basically, "heat movement".
When two objects with the same temperature touch each other what happens to the thermal energy of both objects?
the thermal energy of both will remain constant as there would be no thermal energy transfer
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.
What is the thermal energy that flows from something at a high temperature to somethimg at a lower tempeature?
The thermal energy is stated as the first law of thermodynamics and its the sum of work and heat.
What is the thermal energy of an object?
Thermal energy of an object is the objects amount of kinetic energy.
Why do biological organisms violate the law of thermal dynamics?
No biological entity violates any of the laws of thermodynamics.
Why does thermal energy only move from the warmer object to the cooler object?
Because according to the second law of thermodynamics, energy spontaneously spreads from regions of higher concentration to regions of lower concentration.
Does thermal energy always travel from cooler to warmer objects?
No, thermal energy flows from a high potential to a lower potential. Warmer objects are always at a higher thermal potential than cooler ones, so the energy goes from warm objects to cool ones.
What are two factors that determine an objects thermal energy?
An objects temperature and the number of particles
