  • When heat flows into (or out) a system?

  • 鈼廤hen heat flows into (or out of) a system, the system gains (or loses) an amount of energy equal to the amount of heat transferred. 螖Heat = 螖Internal Energy + Work

  • 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.

  • What is the difference between heat flow and work flow?

  • Heat flow is considered positive when heat flows (into, out of) a system; work is considered positive when work is done (by, on) a system. 1. out of; by 2. into; on 3. out of; on 4. into; by Heat flow q is considered positive when heat flows into a system. Work w is considered positive when work is done on a system.

  • What is the relationship between internal energy and heat flow?

  • If heat flows into a system or the surroundings to do work on it, the internal energy increases and the sign of q or w is positive. Conversely, heat flow out of the system or work done by the system will be at the expense of the internal energy, and will therefore be negative.
