Heat Transfer in Thermodynamics

Very Easy General Chemistry Thermodynamics And Thermochemistry

Thermodynamics is the branch of chemistry that deals with the relationships and conversions between heat and other forms of energy. One of the fundamental concepts is the idea of heat transfer between systems. When two systems are in thermal contact, heat flows from the hotter system to the cooler system until thermal equilibrium is reached.

Which of the following statements regarding heat transfer is true?

Heat always flows from a hot object to a cold object.

Heat can spontaneously flow from a cold object to a hot object.

Heat is a substance that is transferred between objects.
