Q: Is heat energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter? ¶
Q: Is heat a physical property? ¶
A: Yes, and which means that it depends on the substance under consideration and its state as specified by its properties.
Q: Is heat measured by its effect on the states of interacting bodies? ¶
A: Yes, for example, by the amount of ice melted or a change in temperature.
Q: Is heat defined with respect to a specific chosen state variable of the system? ¶
A: Yes, such as pressure or volume.
Q: Is heat that the transfer is entirely due to disordered? ¶
A: Yes, and microscopic action, including radiative transfer.
Q: Is heat the heat released or absorbed by a chemical substance or a thermodynamic system during a change of state that occurs without a change in temperature? ¶
Q: Is heat conventionally written as Q for algebraic purposes? ¶
Q: Is heat examined in the Wikipedia article on calorimetry? ¶
Q: Is heat defined following Carathéodory and Born, solely as occurring other than by work or transfer of matter? ¶
A: Yes, temperature is advisedly and deliberately not mentioned in this now widely accepted definition.
Q: Is heat irreversible? ¶
Q: Is heat one of the forms of energy? ¶
Q: Is heat not specified directly in terms of the non-adiabatic process? ¶
Q: Is heat an appropriate and natural primitive for thermodynamics was already accepted by Carnot? ¶
Q: Was heat measured by changes in the states of the participating bodies? ¶
Q: Is heat the energy transfer associated with a disordered? ¶
A: Yes, and microscopic action on the system, associated with jumps in occupation numbers of the energy levels of the system, without change in the values of the energy levels themselves.
Q: Is heat not a function of state? ¶
Q: Is heat explained in terms of the microscopic motions and interactions of constituent particles? ¶
A: Yes, such as electrons, atoms, and molecules.
Q: Is heat a transfer quantity? ¶
A: Yes, and is described by a transport theory, not as steadily localized kinetic energy of particles.
Q: Is heat considered as a derived quantity? ¶
Q: Is heat measured by changes in a body of known properties? ¶
A: Yes, for example, temperature rise, change in volume or length, or phase change, such as melting of ice.
