Q: Is heat the amount of energy that transfers from a warmer object to a cooler one? ¶
A: Yes.
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 one of the forms of energy? ¶
A: Yes.
Q: Was heat measured by changes in the states of the participating bodies? ¶
A: Yes.
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.
Q: Is heat transferred between two objects or systems? ¶
A: Yes, and the energy of the object or system's particles increases.
Q: Is heat irreversible? ¶
A: Yes.
Q: Is heat a consequence of the microscopic motion of particles? ¶
A: Yes.
Q: Is heat that the transfer is entirely due to disordered? ¶
A: Yes, and microscopic action, including radiative transfer.
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 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? ¶
A: Yes.
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 an appropriate and natural primitive for thermodynamics was already accepted by Carnot? ¶
A: Yes.
Q: Is heat related to the concept of entropy? ¶
A: Yes.
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 often contrasted with work: heat applies to individual particles , work applies to objects? ¶
A: Yes, Heat involves stochastic motion equally distributed among all degrees of freedom, while work is directional, confined to one or more specific degrees of freedom.
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 defined with respect to a specific chosen state variable of the system? ¶
A: Yes, such as pressure or volume.
Q: Is heat not a function of state? ¶
A: Yes.
Q: Is heat conventionally written as Q for algebraic purposes? ¶
A: Yes.
Q: Is heat considered as a derived quantity? ¶
A: Yes.
Q: Is heat not specified directly in terms of the non-adiabatic process? ¶
A: Yes.
