According to the second law of thermodynamics which is a requirement for thermal energy to flow from colder objects to hotter objects?
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.
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.
What is the name of thermal energy that moves from high tepmerature objects to low trmperature objects?
Can two objects of the same substance have the same temperature but probably have the same thermal energy?
1. The two objects are to be in thermal contact. This means that everything between the two objects must be a conductor. 2. There is to be a temperature difference between the two objects. One must be hotter than the other. Given these two conditions, heat will pass from the hotter to the cooler object. That is one of the fundamental laws of thermodynamics.
What name is given for the transfer of thermal energy from areas of high thermal energy to areas of low thermal energy?
What states that the two system which are in thermal equilibrium with a third system are in thermal equilibrium with each other?
Can two objects of the same substance have the same temperature but probably have different thermal energy?
Yes. Since temperature is the average kinetic energy of all of the particles (i.e., thermal energy/mass) and thermal energy is the total, two objects of different mass and different internal energies can have the same temperature. Also, another way of looking at it: If you have two objects of the same temperature and different masses, and multiply that temperature by the masses of the objects, you will get their thermal energies, which will be different…
