Vedclass · Answer

(A) Heat is defined as the energy in transit between a system and its surroundings or between two systems,occurring solely due to a temperature difference between them. It is a path function,meaning its value depends on the process taken to reach a state,not just the state itself. In thermodynamics,heat $(Q)$ is positive when it is added to the system and negative when it is released by the system.
