  • What is the flow of heat?

  • Heat flow is a results of a temperature difference
    between two bodies, and the flow of heat is zero if TS= TE. Figure 17.1. Heat Flow. Heat
    is not the only way in which energy can be transferred between a system
    and its environment.

  • When heat flows out of a system its value is negative?

  • When what flows into a system it’s value is positive when heat flows out of the system it’s value is negative? heat. apex. What does a negative value for heat represent? The Short Answer = Cooling. What is a endopthermic reaction? An endothermic reaction is a reaction where heat flows from the surroundings in to the system.

  • How is heat transferred in the process of reaching thermal equilibrium?

  • In the process of reaching thermal
    equilibrium, heat is transferred from one body to the other. Suppose
    we have a system of interest at temperature TSsurrounded by an environment with temperature TE. If TS TEheat flows from
    the system to the environment. If TS TEheat flows from the environment into the system.

  • What happens to internal energy when heat is added to system?

  • If heat is added to the system its internal energy will increase; if heat is removed from the system its internal energy will decrease. 17.4.3.
